Abstract

Six new structures of ZnII complexes containing 2,2′-bipyridine (2,2′-bpy) ligands have been determined. Halide anions were used as simple coordinating ligands to form a tetrahedral environment around the ZnII ion. Nitrate and benzoate anions were used as chelating ligands to form an octahedral environment. For non-coordinating ClO4- and bridging SO42- anions, three 2,2′-bpy ligands chelate ZnII to form an octahedral environment, and both ClO4- and SO42- anions occupy empty positions between the metal cations for charge balance. Polymeric structures of the ZnII-2,2′-bpy complexes are produced by hydrogen bonding. [Zn(2,2′-bpy)(O2CC 6H5)2] catalyzed efficiently the transesterification reaction of esters with methanol under the neutral conditions, while the remaining compounds showed very slow conversions.
