Synthesis of novel mixed indium(III) chalcogenolato complexes: Potential precursors for indium chalcogenides
摘要:
Novel organometallic and metal-organic indium complexes, [Et2In(OS2CNMe '' Bu)](2) (1), [In{SeP ' Pr-2)(2)N}(S2CNEt2)(2)] (2) and [In{(SeP ' Pr-2)(2)N}(S2P ' BU2)(2)] (3), have been synthesised and characterised. Compound (1) was formed by the insertion of oxygen atoms into the M-S bonds of thiocarbamate ligands, whereas the mixed-chalcogenide complexes (2) and (3) were prepared by the reaction of Na(S2CNEt2)(2) or Na(S2P ' Bu-2)(2) with In[(SeP ' Pr-2)(2)N](2)Cl. The structures of all three compounds were determined by X-ray single crystallographic methods. The dimeric structure of (1) consists of two five membered and one four membered rings formed by chelating and bridging of both dithioperoxycarbarnato ligands. The structures of both (2) and (3) are based on monomers in each case the coordination around indium is distorted octahedral. (c) 2005 Elsevier Ltd. All rights reserved.
