Four Zn(II) and Cd(II) complexes with two kinds of terpyridines have been synthesized and characterized. All these complexes are six N coordinated with two terpyridines. 3-D networks have been formed with hydrogen bonds and pi-pi interactions. The luminescence properties have been studied and all these ligands and complexes can be used as luminescence materials.
