TL;DR: In the absence of solvent, the redistribution of 2 1 and 1 2 molar mixtures of Ph 3 Sb and SbX 3, where X = Cl or Br, is rapid giving quantitative yields of Ph 2 Sb X and PhSbX 2, respectively as mentioned in this paper.

TL;DR: Several antimony trichloride tris(dialkylphosphorodithioates) Sb[S 2 P(OR) 2 ] 3 (R = Me, Et, I-Pr, n-Bu, i-Bu and sec-Bu) have been prepared by reactions between antimony and respectively the ammonium and sodium salts of the corresponding acid.

TL;DR: In this paper, the presence of only weak interactions between the axial chlorine atoms of Ph3SbCl2 and adjacent SbCl3 molecules was found to give polymeric chains parallel to the a axis.
Abstract: Triphenylantimony dichloride reacts with both antimony(III) and antimony(V) chloride to give addition compounds with the stoicheiometry Ph3SbCl2·SbCl3 and Ph3SbCl2·SbCl5, respectively. X-Ray analysis of the former shows the presence of only weak interactions between the axial chlorine atoms of Ph3SbCl2 and adjacent SbCl3 molecules to give polymeric chains parallel to the a axis. The trigonal bipyramidal geometry of Ph3SbCl2 is little changed; co-ordination about SbIII is square pyramidal with three short (mean 2.337 A) and two long (mean 3.262 A) distances. In the SbCl5 compound there is a chloride ion transfer to SbCl5 giving a structure best described in terms of the ionic formulation [Ph3SbCl]+[SbCl6]–. Residual anion–cation interaction is shown by a Cl ⋯ Sb contact of 3.231 A, and the cation geometry is intermediate between the trigonal pyramidal and tetrahedral extremes. Reactions between Ph3SbX2(X = F, Br, or I) and SbCl3, SbBr3, or SbCl5 are also described.
