The novel copper (II) coordination polymer decorated with copper (II) monomer of general formula, [{Cu(ONO2)2(4,4′-bpy) (py)2}·{Cu(ONO2)2(Py)4}] n (CuCP) has been obtained from one pot reaction between 4,4′-bipyridine (4,4′-bpy), pyridine (py) and Cu(NO 3)2·3H2O. The structural and spectural properties have been analyzed by FT-IR, UV-vis, 1H NMR, single crystal X-ray techniques. Besides, the magnetic susceptibility and thermal properties have also been studied. © 2014 Elsevier B.V. All rights reserved.
