Synthesis, crystal structure and magnetic property of copper(II) complex with 4′-cyanobenzyl-1-imidazol

A neutral mononuclear complex [Cu(cbIM)(4)(NO3)(2)] (cbIm=4'-cyanobenzyl-1-imidazol) was synthesized and characterized by x-ray crystallography. It crystallizes in the triclinic space group P-1 with a=8.249(2), b=8.735(2), c=16.597(2) Angstrom, alpha=81.980(10), beta=88.540(10), gamma=63.570(10)degrees and Z=2. The final refinement of the structure leads to R and Rw of 0.0394 and 0.0991, respectively. The crystal structure of the complex indicates a distorted octahedral environment around the Cu(II) atom, coordinated by four imidazole N atoms of four cbIm and two O atoms of two nitrates. Magnetic measurements show that the complex exhibits Curie behavior.
