Coordination Chemistry of Isomeric Mixtures of Linked Di(phosphaguanidine) Compounds: A Spectroscopic and Crystallographic Study

Abstract

Multinuclear NMR spectroscopy and X-ray diffraction techniques have been used to identify diastereomeric mixtures of rac- and meso-di(phosphaguanidine) compounds. A brief survey of their coordination chemistry has demonstrated the formation of N,N'-bound bimetallic aluminum species and monometallic platinum complexes in which the ligand chelates to the metal through the two phosphorus donor atoms.
