Reactions of Antimony(III) Chloride Adducts with

Abstract

A number of adducts of antimony trichloride have been prepared

with O, N, S-donor atoms. These adducts have been treated with

KCNS in THF when substitution of the chlorine atoms in the adduct

occurs with SCN group resulting in the formation of antimony

trithiocyanate adducts. The ambidentate SCN group attaches to

antimony through nitrogen in some complexes (naphthalene,

anthracene, phenanthrene, pyridine, bipyridyl, 1,10-phenanthroline,

methylcyanide) and through sulphur in the other adducts(formamide,

dimethyl formamide, acetamide, benzamide, acetanilide,

triethylamine. aniline, o-, m-, p-toluidine, dimethyl aniline, urea,

thiourea, DMSO).
