Sodium antimonide

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.

Alkyl-combination.— Antimony hydride (SbHg), like arsenic hydride (AsHg) and phosphorus hydride (PH,), can give rise to organic compound in which the H-component is replaced by an alkyl. It is then called stibine. It can be produced by allowing iodine-alkyls to act upon potassium antimonide or upon sodium antimonide, or by the reaction between antimony chloride and zinc-alkyls.

No, the editor didn t know what this name meant either.) It means salts of the triva-lent anions of Group V, restricted in [1] to arsenides, antimonides and bismuthides and prepared by reaction of sodium pnictides with anhydrous halides of transition and lanthanide metals. This violently exothermic reaction may initiate as low as 25°C. Avoidance of hydrated halides is cautioned since these are likely to react uncontrollably on mixing. Another paper includes a similar reaction of phosphides, initiated by grinding [2], Nitrides are reported made from the thermally initiated reaction of sodium azide with metal halides, a very large sealed ampoule is counselled to contain the nitrogen [3],...

One method for the synthesis of cyclic silicon-phosphorus compounds is the reaction of alkaliphosphides with dichlorosilanes [1]. Using sodium/potassium phosphide, -arsenide, -antimonide and -bismutide Na3E/K3E (E = P, As, Sb and Bi) [2] with various di-, tri-, and tetrachloroorganosilanes, cages of the following types (Fig 1.) have been synthesized so far. 

Uranous Antimonide, UgSb4, is not obtained by the ordinary methods used for the arsenide (see p. 332). By fusing a mixture of sodium uranous chloride, antimony, and aluminium Colani obtained a silvery white mass practically free from aluminium. The product resembled the phosphide and arsenide in properties, and produced vivid sparks when projected into the Bunsen flame.

Reactions of antimony monocycles with alkali metals have been studied in the case of the reactions of (PhSb)g with sodium in liquid ammonia. According to the molar ratio of the reagents two different antimonides, PhSbNa2 and NaSb(Ph)Sb(Ph)Na, were obtained. These antimonides proved to be synthetically useful and, with organic halides, the expected stibanes or distibanes were formed. For example, the reaction of the antimonides with EtBr gave PhSbEtj and Et(Ph)SbSb(Ph)Et, respectively .

Hydrogen Antimonid—Stibin—Antimoniuretted hydrogen— Stibamin—Stibonia—SbHi—138.—It has not been obtained in a condi tion of purity, but is prod need, mixed with H, when a reducible compound of Sb is in presence of nascent H. It is obtained in larger amount, by decomposing an alloy of 400 parts of a 3 sodium amalgam, and 8 parts of freshly reduced, and dried Sb, by HaO, in a current of COa. 

A neutralization of impurities is probably what takes place when brass and red brass are treated with sodium. The cleanser is usually introduced as a zinc-sodium master alloy. Zinc dissolves not more than 2.8% sodium at 557° C. and this alloy, when solid, is constituted of zinc-sodium compound in a zinc matrix. An action of sodium on sulfides, antimonides, and arsenides, even if these impurities were tied up with zinc, could be expected in these copper alloys. Sodium has been suggested as a desulfurizer for cast iron and shooting it into the metal bath has been proposed. In another proposition the sodium is weighed down with lead within an iron shell with a perforated bottom, which is lowered into the fused cast iron. Evidently sodium-lead alloy would perform as well.
