Organo-gallium and indium complexes with dithiolate and oxo ligands: Synthesis, structures and applications

Abstract

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∩S)3], [RM(S∩S)2] and [R2M(S∩S) ] (where R = Me or Et; M = Ga or In; S∩S = RCS2, ROCS 2, R2NCS2 and (RO)2PS2) have been isolated. Reactions of internally functionalised oxo ligands with R3M·OEt2 afforded diorganometal complexes [R 2ML]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 β-In2s3 nanoparticles. © Indian Academy of Sciences.
