In(SPh)3 is readily prepared by the reaction of InCl3 and NaSPh in methanol.The compound is a Lewis acid, forming 1:1 adducts with 2,2'-bipyridine, 1,10-phenanthroline.N,N,N',N'-tetramethylethanediamine, bis(diphenylphosphino)ethane, and dimethylsulphoxide, and 1:2 adducts with pyridine, trimethylamine, and triphenylphosphine.Reaction with R4NX (X=Cl, Br, I) or similar salts gives R4N salts, which are 1:1 electrolytes.The structure of Ph4P has been determined by X-ray methods.The crystals are monoclinic, space group P21/c, with cell dimensions a=9.964(3) Angstroem, b=13.477(3) Angstroem, c=30.359(7) Angstroem, α=98.30(2) deg, Z=4, R=0.0622 for 2924 unique observed reflections.The anion has distorted tetrahedral symmetry In the InBrS3 kernel, In-Br=2.527(2) Angstroem, and In-S(av)=2.450 Angstroem.The vibrational spectra of In(SPh)3 and its derivatives in the region 500-200 cm-1 are discussed.
