Coordination chemistry of scandium—I. Synthesis and crystal structure of scandium six-coordinate glycine complex [Sc 2(Gly) 6(ClO 4) 6] n

Abstract

The title complex was synthesized in an aqueous solution of SC(ClO 4) 3, and its crystal structure was determined by an X-ray diffraction method. The complex has an infinite chain structure, built from dimeric units. Two scandium ions are combined by three simple bridging carboxyl groups from three glycine molecules. Only one type of bonding mode of the carboxyl groups is represented. Scandium exhibits an octahedral configuration.
