Crystal structures of complexes with zwitterionic ligands
Abstract
Crystal structure analysis of two copper(II) complexes of a betaine have shown that Cu(Me3NCH2–CO2–)2(CIO4)2 contains a copper-copper bond, has bridging bidentate carboxy-groups, and both ionic and co-ordinated perchlorate, while Cu(Me3NCH2CO2–)4(CIO4)2 is monomeric and has only ionic perchlorate.
