Tris(benzenethiolato)indium(III) (In(SPh)3) has been facilely prepared in high yield of 95.0% by a microwave-assisted solvothermal reaction of indium and diphenyl disulphide in methanol in 15 min. The combination of In(SPh)3 as precursor with dipyridyl ligands of bipy (bipy = 4,4′-bipyridine) and dpp (dpp = 1,3-di(4-pyridyl)propane) in methanol at ambient conditions yielded two new compounds, namely In(SPh)3(bipy) (1) and In(SPh)3(dpp) (2), respectively. Single-crystal X-ray crystallographic studies reveal that in both the structures, the five-coordinated In(III) ions in nearly perfect trigonal-bipyramidal geometry are interconnected by the bifunctional dipyridyl ligands to form one-dimensional chains. Their thermal properties have been investigated.

The tris(arylthiolate)indium(III) complexes (4-RC6H 4S)3In [R = H (5), Me (6), F (7)] were prepared from the 2:3 reaction of elemental indium and the corresponding aryl disulfide in methanol. Reaction of 5-7 with 2 equiv of the appropriate triorganylphosphine in benzene or toluene resulted in isolation of the indium-phosphine adduct series (4-RC6H4S)3In·PR′3 [R = H, R′ = Et (5a), Cy (5b), Ph (5c); R = Me, R′ = Et (6a), Cy (6b), Ph (6c); R = F, R′ = Et (7a), Cy (7b), Ph (7c)]. These compounds were characterized via elemental analysis, FT-IR, FT-Raman, solution 1H, 13C{1H}, 31P{1H}, and 19F (7a-c) NMR spectroscopy, and X-ray crystallography (5c, 6a, 6c, and 7a). NMR spectra show retention of the In-P bond in benzene-d6 solution, with phosphine 31P{1H} signals shifted downfield compared to the uncoordinated ligand. The X-ray structures show monomeric 1:1 adduct complexes in all cases. The In-P bond distance [2.5863(5)-2.6493(12) A] is influenced significantly by the phosphine substituents but is unaffected by the substituted phenylthiolate ligand. Relatively low melting points (88-130°C) are observed for all adducts, while high-temperature thermal decomposition is observed for the indium thiolate reactants 5-7. DSC/TGA and EI-MS data show a two-step thermal decomposition process, involving an initial loss of the phosphine moiety followed by loss of thiolate ligand.

Indium reacts with both Ph2S2 and Ph2Se2 in refluxing toluene to give the compounds In(EPh)3 (E = S or Se) in high yield.Under similar conditions tin gives Sn(EPh)4.Thallium reacts with Ph2Se2 to form Tl(SePh), but does not react with Ph2S2.Neither zinc nor gallium reacts with Ph2S2 or Ph2Se2.With mixtures of Ph2E2 and I2, indium yields the previously unreported InI(EPh)2 compounds.The reactions of In(SePh)3 are those of a typical indium(III) Lewis acid.Possible factors affecting the reactions of metals with Ph2S2 or Ph2Se2 are briefly discussed.
