In oxidation states lower than f4,only Ti”’
forms a sulfate and this gives rise to the alums, MTi(S04)2.12H20 (M = Rb, Cs), containing the octahedral hexaaquotitanium(II1) ion.
Octahedral, anionic complexes, [MX6I2-, show a marked increase in susceptibility to hydrolysis and consequent difficulty in preparation, in passing from the stable fluorides to the heavier halides, with the result that the hexaiodo complexes cannot be isolated. The fluorozirconates and fluorohafnates display considerable variety, complexes of the types [MF7I3-, [M2F14I6-, and [MF8I4- having been prepared, often by fusion of the appropriate fluorides. In Na3ZrF7 the anion has the 7-coordinate pentagonal bipyramidal structure; in Li6[BeF4][ZrFs] the zirconium anion is 8-coordinate, dodecahedral (distorted); in Cu6[ZrF8].12H20 it is 8-coordinate, square antiprismatic, and in Cu3[Zr~F14]1.8HzO dimerization by the edge-sharing of two square antiprisms maintains 8-coordination. Stoichiometry does not, however, define coordination type, and this is very well illustrated by the ostensibly [MF6I2- complexes which may contain 6-, 7-, or 8-coordinate Zr“ or Hf’“ depending on the counter anion. In RbzMF6, M is indeed octahedrally coordinated, but in (NH4)2MF6 and KzMF6 polymerization occurs to give respectively 7- and 8-coordinate species.

26.3.4 The biochemistry of ~ o b a l t ( ~ ~ )
The wasting disease in sheep and cattle known variously as “pine” (Britain), “bush sickness” (New Zealand), “coast disease” (Australia), and “salt sick” (Florida) has been recognized since the late eighteenth century. When it was realized to be an anaemic condition it was thought to be due to iron deficiency and was therefore treated, with mixed success, by administering iron salts. Then, in the 1930s, it was found by workers in Australia and New Zealand that the efficacious principle in the iron treatment was actually an impurity (cobalt) but its role was not understood. This became more evident when vitamin BIZwas extracted from raw liver and shown to be responsible for the latter’s well-known effectiveness in treating pernicious anaemia. It is now known that vitamin B12 is a coenzyme? in a number of biochemical processes, the most important of which is the formation of erythrocytes (red blood-cells). It obviously functions extremely effectively, the human body for instance containing a mere

ores such as arsenopyrite, FeAsS. Sb2O3 and Bi203 are made similarly. All 3 oxides exist in several modifications as shown in the schemes on p. 573.(16)In the vapour phase As203 exists as As406 molecules isostructural with P4O6 (p. 504), and this unit also occurs in the cubic crystalline form. Above 800" gaseous As406 partially dissociates to an equilibrium mixture containing both As406 and As203 molecules. The less-volatile monoclinic form of As203 has a sheet-like structure of pyramidal {As03}groups sharing common 0 atoms. This transformation from molecular As406 units to polymeric As203 is accompanied by an 8.7% increase in density from 3.89 to 4.23gcmP3. A similar change from cubic, molecular Sb4O6 to polymeric SbzO3 results in an 11.3% density increase from 5.20 to 5.79 g ~ m - ~ .

showing only slight reactivity towards alkali. It gradually decomposes, however, to Fe304 with evolution of hydrogen and in the presence of oxygen darkens rapidly and eventually forms the reddish-brown hydrated iron(II1) oxide. Fe304 is a mixed Fe"/Fe"' oxide which can be obtained by partial oxidation of FeO or, more conveniently, by heating Fez03 above about 1400°C. It has the inverse spinel structure. Spinels are of the form M"M!'04 and in the normal spinel (p. 247) the oxide ions form a ccp lattice with M" ions occupying tetrahedral sites and M"' ions octahedral sites. In the inverse structure half the MI" ions occupy tetrahedral sites, with the M" and the other half of the M"' occupying octahedral sites.? Fe304 occurs naturally as the mineral magnetite or lodestone. It is a black, strongly ferromagnetic substance (or, more strictly, "ferrimagnetic" - see p. lOSl), insoluble in water and acids.

These elements, with their unique properties and combinations, create a symphony of nature that is both beautiful and intricate. Starting from the lightest element, hydrogen, we see the simplicity and elegance of nature. It is the most abundant element in the universe, forming stars and powering their radiance. Moving up the periodic table, we encounter elements like carbon, the backbone of all known life. Its ability to form long chains and complex structures gives rise to molecules that are the essence of organic matter. Oxygen, another crucial element, sustains life on Earth by supporting respiration and combustion. Its reactive nature allows it to bond with other elements, creating oxides that are essential in many chemical processes. Metals like iron and copper, with their unique electrical and thermal properties, have been used for centuries in tools, weapons, and structures.The periodic table, a concise representation of all known chemical elements, is a testament to the orderly nature of the universe. It reveals patterns and relationships between elements, guidingscientists in their quest to understand and manipulate matter.The study of chemical elements is not just about understanding their properties and reactions. It is also about appreciating the beauty and harmony that exist in nature. From the sparkle of a diamond, a pure form of carbon, to the rusting of iron, a natural oxidation process, we see the wonders of chemistry unfolding in our daily lives.In conclusion, the magic of chemical elements lies in their ability to create and sustain life, to power the universe, and to inspire us to explore and understand the fundamental building blocks of our existence.

Arsenic, Antimony and Bismuth
Ch. 73
assigning precise dates to discoveries made by alchemists, miners and metal workers (or indeed even discerning what those discoveries actually were), it seems clear that As, Sb and Bi became increasingly recognized in their free form during the thirteenth to fifteenth centuries; they are therefore contemporary with Zn and Co, and predate all other elements except the 7 metals and 2 non-metallic elements known from ancient times (Au, Ag, Cu, Fe, Hg, Pb, Sn; C and S).'')

Arsenic, Antimony and Bismuth
13.1 Introduction
The three elements arsenic, antimony and bismuth, which complete Group 15of the periodic table, were amongst the earliest elements to be isolated and all were known before either nitrogen (1772) or phosphorus (1669) had been obtained as the free elements. The properties of arsenic sulfide and related compounds have been known to physicians and professional poisoners since the fifth century BC though their use is no longer recommended by either group of practitioners. Isolation of the element is sometimes credited to Albertus Magnus (AD 1193-1280) who heated orpiment (AS&) with soap, and its name reflects its ancient lineage. [Arsenic, Latin arsenicum from Greek & ~ ~ V L K(a~rsVenicon) which was itself derived (with addition of 6 v ) from Persian az-zarnTkh, yellow orpiment (zar = gold).] Antimony compounds were also known to the ancients and the black sulfide, stibnite, was used in early biblical times as a cosmetic to darken and beautify women’s eyebrows; a rare Chaldean vase of cast antimony dates from 4000 BC and antimony-coated copper articles were used in Egypt 2500-22OOBC. Phny (-AD 50) gave it
Arsenic minerals are widely distributed throughout the world and small amounts of the free element have also been found. Common
' M. E. WEEKS, Discovery of the Elements, Chap. 3,
the name stibium and writings attributed to Jabir (-AD 800) used the form antimonium; indeed, both names were used for both the element and its sulfide until the end of the eighteenth century (Lavoisier). The history of the element, like that of arsenic, is much obscured by the intentionally vague and misleading descriptions of the alchemists, though the elusive Benedictine monk Basil Valentine may have prepared it in 1492 (about the time of Columbus). N. Lkmery published his famous Treatise on Antimony in 1707. Bismuth was known as the metal at least by 1480 though its previous history in the Middle Ages is difficult to unravel because the element was sometimes confused with Pb, Sn, Sb or even Ag. The Gutenberg printing presses (1440 onwards) used type that had been cut from brass or cast from Pb, Sn or Cu, but about 1450 a secret method of casting type from Bi alloys came into use and this particular use is still an important application of the element (p. 549). The name derives from the German Wismut (possibly white metal or meadow mines) and this was latinized to bisemutum by the sixteenth-century German scientist G. Bauer (Agricola) about 1530. Despite the difficulty of

the sulfide residues can be released by roasting them in air and trapping the sublimed As203 in the flue system. The oxide can then either be used directly for chemical products or reduced with charcoal at 700-800" to give more As. As203 is also obtained in large quantities as flue dust from the smelting of Cu and Pb concentrates; because of the huge scale of these operations (pp. 1174, 371) this represents the most important industrial source of As. Some production figures and major uses of As and its compounds are listed in the Panel.
pp. 91-119, Journal of Chemical Education, Easton, Pa, 1956.
minerals include the two sulfides realgar (AsqS4) and orpiment (As&) and the oxidized form arsenolite (As203). The arsenides of Fe, Co and Ni and the mixed sulfides with these metals form another set of minerals, e.g. loellingite (FeAs2), safforlite (CoAs), niccolite (NiAs), rammelsbergite (NiAs2), arsenopyrite (FeAsS), cobaltite (CoAsS), enargite ( C U ~ A S Sg~e)r,sdorffite (NiAsS) and the quaternary sulfide glaucodot [(Co,Fe)AsS]. Elemental As is obtained on an industrial scale by smelting FeAs2 or FeAsS at 650-700°C in the absence of air and
