Abstract

A mononuclear copper(II) complex, [Cu(dmpp)(OCN)2(H 2O)], was synthesized using 2,6-bis (3,5-dimethylpyrazolyl) pyridine (dmpp) and cyanate anion (OCN), and characterized by single crystal X-ray diffraction. The coordination around the Cu atom is a distorted square-pyramid involving three N atoms from the dmpp ligand and one N atom from OCN at the basal plane. The O atom of the OCN group is located at the apical position.The Cu atom is located 0.2782(1) Å above the basal plane. The Cu atom is coordinated by different donor atoms of the OCN groups. The complex crystalizes in monoclinic space group P21/n, with unit cell dimensions a= 12.4413(12), b=11.1457(13), c=14.2203(12) Å, β=108.817(3)°, V= 1866.5(3) Å3. The cell centaines 4 molecules. In the crystal, there are three intermolcular and three intramolecular hydrogen bonds interactions. The Cu atom and crystal water O interactions is 5.574 Å. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
