Synthesis and structural characterization of a new one-dimensional chain coordination polymer of copper(II) with diethylenetriamine and 1,3-bis(imidazol-1-ylmethyl)-5-methylbenzene

A novel one-dimensional coordination polymer, {[Cu(dien)(dimb)](ClO4)2}n [dien=diethylenetriamine; dimb=1,3-bis(imidazol-1-ylmethyl)-5-methylbenzene] was synthesized by treatment of [Cu(dien)(im)](ClO4)2 (im=imidazole) with the dimb ligand. The complex was characterized by X-ray crystallography and electrospray mass spectrometry. The coordination geometry around Cu(II) is distorted square-based pyramid with N5 donor set.
