Bis(μ-5-carboxylatotetrazolido)bis[aqua(2,2′-bipyridyl)cadmium(II)]

Abstract

In the title dinuclear CdII complex, [Cd2(C2N4O2)2(C10H8N2)2(H2O)2], each Cd atom is in a slightly distorted octahedral coordination by two N atoms and one O atom of two 1H-tetrazole-5-carboxylate (TZC) ligands, two N atoms of a 2,2′-bipyridyl ligand and one water O atom. The TZC ligand acts in a tridentate N,O-chelating N-bridging mode to two symmetry-equivalent CdII atoms. The complex reveals molecular Ci symmetry. Extensive O—H...O hydrogen bonding plays an important role in the crystal packing.
