Reaction of PR 3, R = cyclohexyl (Cy), cyclopentyl (Cy p) or phenyl, with [lnH 3(NMe 3)] affords the 1:1 indium trihydride complexes, [InH 3(PR 3)]. The stabilities and spectroscopic properties of these complexes are described in terms of the phosphine ligands' steric bulk and nucleophilicity. Reaction of two equivalents of PCy 3 with [InH 3(NMe 3)] yields the complex [InH 3(PCy 3) 2] which has been characterised by X-ray crystallography. The first phosphido-indium hydride complex, [{InH 2(PCy 2)} 3], has been prepared by a novel synthetic route which involves treatment of [InH 3(NMe 3)] with LiPCy 2, Its crystal structure shows it to exist as a cyclic trimer in the solid state. The complex, [InH 3(PCy 3)] has been used to prepare a range of monomeric indium chalcogenolato complexes, [In(EPh) 3(PCy 3)], E = S, Se or Te, all of which have been structurally characterised. '
