Methanol(2-methyl-1H-imidazole-κN³)(pyridine-2,6-dicarboxylato-κ³N,O,O′)copper(II)

Abstract

In the title compound, [Cu(C7H3NO4)(C4H6N2)(CH4O)], the Cu atom lies in the centre of an N2O2 square plane, and the methanol mol­ecule is apically coordinated. The coordination geometry is best described as distorted square‐pyramidal. There are intermolecular hydrogen bonds in the crystal structure, which mediate the formation of layers.

“…Attention has been paid to the design of various Ndonor ligands with special structural properties in order to investigate the specific stereochemical requirements of a particular metal-binding site (Mukherjee, 2000). Various substituted N-donor heterocyclic ligands such as imidazole and pyrazole have been selected as a second ligand, so that the structural and electronic effects on the biologically important Cu-N bond could be probed (Ang et al, 1991;Chen et al, 2011;Lin et al, 2009;Liu et al, 2005). As part of these continuing studies, the title complex has been synthesized and characterized by single crystal X-ray diffraction.…”
