Coordination Compounds of Indium. Part XXVII. Addition Compounds of Acetato(dimethyl)indium(III)

Abstract

The compound Me 2 In(OAc), which is polymeric in the crystalline state, reacts with neutral donor ligands in organic solvents to yield three series of adducts. With monodentate donors, the product is Me 2 In(OAc)L (L = dimethylsulfoxide or pyridine), which is formulated as a five-coordinate monomer in solution. With bidentate donors, the product is either the monomeric six-coordinate Me 2 In(OAc)L II (L II = ethylenediamine or 1,2-bis(diphenylphosphino)ethane), or the complex [Me 2 In(OAc)] 2 L II (L II = 2,2′-bipyridyl or 1,10-phenanthroline). The n.m.r. and vibrational spectra of these compounds are discussed.
