Abstract
Abstract Trichlorobis(hexamethylphosphoramide)In(III), InCl3(OP(N(CH3)2)3)2, was prepared by extraction of indium(III) chloride from aqueous solution into chloroform containing a slight excess of hexamethylphosphoramide and structurally characterized by X-ray methods. In this pentacoordinated complex, the central In(III) ion is bonded to two hexamethylphosphoramide molecules via the phosphoryl oxygens in the axial positions and to three chloride ions in the equatorial positions in a trigonal bipyramidal arrangement with average InO and InCl bond distances of 2.18 and 2.36 A respectively. The solid state infrared and Raman spectra of the complex are discussed. The observed spectra are consistent with those expected for the pentacoordinated structure of the complex.
