Özet

Polymeric copper(II) complex, [Cu(Hacm)(2)(na)(2)(H2O)(2)] [H(2)acm: acetazolamide, na; nicotinamide] was synthesized and characterized by spectroscopic (IR; infrared spectroscopy, EPR: electron paramagnetic resonance), structural (XRD) and voltammetric structural (CV) methods. The copper(II) compound crystallizes in the triclinic space group P (1) over bar, Z=1, with the unit-cell dimensions: a = 7.672 (5)angstrom, b = 8.681 (5)angstrom, c = 11.938 (5)angstrom, alpha = 90.807 (7)degrees, beta = 98.616 (5)degrees and gamma = 110.647 (5)degrees. The Cu(II) ion has a distorted octahedral coordination geometry. The crystal packing of the complex is stabilized by intermolecular O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds. The powder EPR spectrum of copper(II) complex have indicate that the paramagnetic center is in a tetragonal symmetry with the Cu2+ ion having a distorted octahedral geometry. The vibrational investigation has been carried out on the basis of some characteristic IR bands of acetazolamide and nicotinamide molecules. (C) 2012 Elsevier B.V. All rights reserved.
