Compounds of Antimony

Metallic Antimonides. Numerous binary compounds of antimony with metallic elements are known. The most important of these are indium antimonide [1312-41 -0] InSb, gallium antimonide [12064-03-8] GaSb, and aluminum antimonide [25152-52-7] AlSb, which find extensive use as semiconductors. The alkali metal antimonides, such as lithium antimonide [12057-30-6] and sodium antimonide [12058-86-5] do not consist of simple ions. Rather, there is appreciable covalent bonding between the alkali metal and the Sb as well as between pairs of Na atoms. These compounds are useful for the preparation of organoantimony compounds, such as trimethylstibine [594-10-5] (CH2)2Sb, by reaction with an organohalogen compound. 

Compounds of antimony have been used as therapeutic agents for thousands of years (200). There is evidence that the ancient Egyptians used a... 

Treatment of tervalent compounds of antimony with perchloric acid can be very hazardous. 

Some compounds of antimony appear to involve the +4 oxidation state. For example, an oxide of antimony is known that has the formula Sb204, but this oxide actually contains equal numbers of Sb(III) and Sb(V) atoms. The chloride complex Sb2Cl102 also contains Sb(III) and Sb(V) rather than Sb(IV).

The writings of Sylvius were first published between 1659 and 1674, all on medical subjects primarily, unless we except his brief treatise on Chemical Medicines,10 which is practically confined to the various medicinal compounds of antimony— flowers, liver, regulus, glass, antimony diaphoreticum, butter of antimony, the latter made by distilling crude antimony (that is sulphide) with mercury sublimate (that is mercuric chloride). These compounds were, however, all known by 1600 and well summarized in pseudo-Basilius s (Tholden s) Currus Tri-umphalis Antimonii. 

Dissolution of the oxides and/or other compounds of antimony present after combustion of the coal sample proved difficult. Radiochemical yields are rather low, ranging from 30 to 55%. The average relative... 

Compounds of antimony are used as fire retardants in plastics and paper, and for veterinary purposes. The metal is found in specialised alloys such as white metal bearings and pewter, which is an alloy of tin, antimony (up to 7.5%) and copper. Concentrations in food are low, generally in the range <0.01 to 0.08 mg/kg, but have been found to be higher in samples of aspic jelly and cream of tartar.40 The... 

It is possible to regard nitric peroxide in this light as a nitrate of nitrosyl, 0=N—NOs but its easy decomposition into NO, when heated militates against the view. Compounds of antimony and bismuth, having the... 

Among the more unusual BCNO compounds is antimony oxide, which is used to fireproof toys, car seats, and airplane parts. The compound reacts with burning material to form a chemical layer that blankets and extinguishes the flame. In ancient times, the Egyptians mixed a compound of antimony and sulfur with fat to make kohl, a black cosmetic used to color eyebrows and line eyes with a dark ring. All living things seem to need a tiny bit of the... 

It is obvious from the literature summarized in recent reviews (11, 26) that very little information is available on ylidic compounds of antimony. Moreover, the few compounds synthesized were all taken from the aryl series, whereas those of the alkyl series appear to be completely unknown. Even the aryl antimony ylides were of very limited thermal stability and could only be isolated in special cases (11).

In Vienna a case of chronic antimony poisoning occurred in a house with silk curtains containing a mordant with a compound of antimony. A series of experiments was performed to detect the possible formation of volatile compounds of antimony, but the speciation of the volatile antimony compound has been unsuccessful .
