stereoselectivity. In these products the complex ligand may act as a tridentate N,N,C donor or, in complexes containing an azaplatinacyclobutane ring, as a tetradentate N,N,N,C donor. The absolute configurations of five (aminoalkyl)platinum(IV) products were determined by X-ray crystal structure determinations and gave a benchmark such that the stereochemistries of other complexes could be assigned by NMR.
