2,2′‐Bipyrimidineoxalatocopper(<scp>II</scp>) Complexes: From the Mononuclear Complex to the 2D Sheetlike Polymer

Abstract

An unusual two-dimensional mesh of CuII ions is found in complex 1(see picture); the metal atoms are bridged by oxalato (ox) and bipyrimidine (bpym) ligands to form ringshaped hexamers. Variable-temperature magnetic susceptibility measurements indicate that antiferromagnetic coupling between the Cu atoms occurs.
