Antimony trichloride also behaves as a Lewis base. However, sucb reactions are very limited. They include the formation of carbonyl complexes Fe(CO)3(SbCl3)2 and Ni(CO)3SbCl3. 

Diammino-antimony Trichloride, [Sb(NH3)2]Cl3.—This derivative is prepared by passing ammonia gas over molten antimony trichloride or warm antimony pentachloride.1 It is a yellowish-white semi-crystalline substance, which is volatile without decomposition and is attacked by hydrochloric acid, with formation of the compound NH4Cl.SbCl3. 

The practice of assuming an increased valency for nitrogen when ammonia unites with hydrogen chloride, says A. Werner, if consistently carried out, would make antimony tervalent in antimony trichloride, and quinquevalent in SbCl3.KCl, etc. Bivalent iron in ferrous cyanide, FeCy2, would become decivalent in potassium ferrocyanide, K4FeCy6. J. Piccard and J. H. Dardel, and P. Pfeiffer discussed this subject. 

The structure of a 2 1 complex between antimony trichloride and phenanthrene consists of alternating double layers of SbCl3 and arene molecules (276). Unlike complex Cl and SbCl3 itself, Sb—Cl contacts between neighboring SbCl3 units are observed in this complex. In both structures mentioned here, vacant coordination sites are observed, which might be occupied by a stereochemically active lone pair at the antimony center.

Antimony Trichloride TS Dissolve 20 g of antimony trichloride (SbCl3) in chloroform to make 100 mL. Filter if necessary. 

It is with Sbm and Bim that really extensive complex formation occurs. Antimony trichloride forms complexes with neutral donors those with PhNH2 have structures showing that the N—Sb bonds are relatively weak and that the lone pair is stereo-chemically active, as illustrated in Fig. 10-6. Antimony trichloride also forms 2 1 and 1 1 complexes with aromatic hydrocarbons such as naphthalene or p-xylene, where weak interaction between SbCl3 and the n cloud occurs. 

The electrodeposition of antimony, Sb, has been reported in both acidic and basic BPCI-AICI3 ionic liquid [28, 29]. Antimony trichloride, SbCl3, is soluble in both acidic and basic ionic liquids. In the case of an acidic ionic liquid, a cationic trivalent antimony species, SbClJ, is formed and can be reduced to the metallic state ... 

The electrodeposition of antimony [77] and indium-antimony [78] alloys has been reported in a basic EMICI-EMIBF4 ionic liquid. Antimony trichloride, SbCl3, dissolves in the ionic liquid and forms SbQ, the same as in the basic chloro-aluminate ionic liquid. Metallic Sb can be obtained by the cathodic reduction of SbCl4, as shown in Eq. (9.14). The formal potential of Sb(III)/Sb is reported as —0.27 V vs. AI/Al(in) in the ionic liquid containing Cl at 0.11 M. In addition the oxidation of SbCl4 leads to the formation of a pentavalent antimony species, SbClg ... 

Antimony trichloride, on the contrary, gave only Ni(CO)3(SbCl3) (203). The direct reaction between Ni(CO)4 and PF3 has been investigated extensively. Chatt (52) obtained a complex mixture from which he could isolate the nearly pure NiCO(PF3)3. Bigorgne (19) studied the same reaction by IR spectroscopy, recognizing that even at 0° C. all four substitution compounds are present together. He isolated and characterized the tetrasubstituted Ni(PF3)4 obtained in this way. 

Mesitylene " and hexaethylbenzene each give 1 1 complexes with half-sandwich structures with antimony trichloride and a similar 1 1 complex is known for the tribromide with mesitylene. The 2 1 adduct of antimony tribromide with biphenyl is centrosymmetric with a molecule of the antimony halide coordinated to each phenyl group and on opposite sides a similar picture is found with 2SbCl3.(2,2 -dithienyl), 2SbBr3-(9,10-dihyd-roanthracene) and 2SbCl3. (pyrene) . In the complex of [2.2.2]paracyclophane with two molecules of SbCl3, two of the benzene rings are almost symmetrically coordinated to antimony . 

Acute respiratory exposure of seven workers to 70-80 mgm" of antimony trichloride, SbCl3, resulted in irritation of the upper respiratory tract. Antimony pentachloride, SbCl5, caused severe pulmonary edema in three cases, two of them being lethal Completed inhalation studies have demonstrated that inhalation of antimony trioxide induces lung tumors in female rats. ...

Arylstibonic acids are formed when arenediazonium salts are decomposed by an alkali antimonite (Sb203 + alkali).519,520 The procedure can be varied by preparing a double salt, e.g., C6H5N2C1 SbCl3 by adding antimony trichloride in acid solution and decomposing the salt by sodium hydroxide solution.
