Methylindium (III) dithiolate complexes of the general formulae [Me₂In(S^∩S)] (1) and [MeIn(S^∩S)₂](2)[S^∩S=(EtO)₂PS₂⁻, (PrⁱO)₂PS₂⁻, Et₂ NCS₂⁻, Prⁱ₂ NCS₂⁻, O(CH₂CH₂)₂ NCS₂⁻, EtOCS₂⁻ and Prⁱ OCS₂ ⁻] have been isolated conveniently by the reaction of Me₃In•OEt₂ with In(S^∩S)₃ (3) in an appropriate stoichiometry. Both 1 and 2 have been characterized by indium analysis, IR, NMR (¹H, ¹³C{¹H} and ³¹P{H}) and mass spectral data. NMR data of 3 are also included for comparison. The Me–In and S^∩S resonances are sensitive to the number of methyl groups attached to indium metal. The mass spectral data indicate that these complexes are monomeric in nature. The thermal behavior of a few complexes has been investigated. The xanthate and dithiocarbamate complexes on pyrolysis under dynamic vacuum or flowing nitrogen atmosphere gave either In₂S₃ or a mixture of InS, In₂S₃ and In₆S₇, which were characterized using EDAX and powder XRD.
