Abstract

Tris(N,N-diisopropylmonothiocarbamato)indium(III), In(SOCNiPr2)3, has been prepared by the reaction of indium(III) chloride and lithium N,N-diisopropylmonothiocarbamate. In the solid state, the complex is a distorted trigonal prismatic monomer with a meridional configuration, as characterised by single-crystal X-ray diffraction. In(SOCNiPr2)3 has been used as a single-source precursor for the deposition of tetragonal β-In2S3 thin films by low pressure metal-organic chemical vapour deposition (LP-MOCVD) at temperatures ranging from 300 to 450[thin space (1/6-em)]°C, on borosilicate glass substrates.
