The chemistry of organo-gallium and indium complexes with dithiolate and internally functionalised oxo ligands has been explored. With 1,1-dithiolate ligands both classical and organometallic complexes of gallium and indium, [M(S$^\cap$S)3], [RM(S$^\cap$S)2] and [R2M(S$^\cap$S)] (where R = Me or Et; M = Ga or In; S$^\cap$S = RCS2, ROCS2, R2NCS2 and (RO)2PS2) have been isolated. Reactions of internally functionalised oxo ligands with R3MR$\cdot$OEt2 afforded diorganometal complexes [R2ML]$_n$. Molecular structures of several of these complexes have been established by single crystal X-ray diffraction analyses. Complexes derived from oxo ligands showed photoluminescence. They have been used as alkylating agents for C-C coupling reactions of aryl bromides in the presence of PdCl2(PPh3)2. Indium dithiolate complexes have been used as molecular precursors for the preparation of mono dispersed ẞ-In2S3 nanoparticles.
