Abstract
The crystal and molecular structure of [Cu(tzpy)2(ONO2)2(OH2)] (tzpy=3-methyl[1,2,3]triazolo[1,5-a]pyridine) has been determined by X-ray diffraction methods. The crystal structure is built up of discrete [Cu(tzpy)2(ONO2)2(OH2)] entities linked through hydrogen bonds. The coordination geometry around the copper atom can be described as an elongated and strongly distorted octahedron displaying a 4+1+1* coordination mode (CuN2O2O′O″ chromophore), with one of the nitrato groups acting as bidentate and involved in a weak off-the-z-axis coordination. Spectroscopic properties are interpreted on the basis of the above stereochemistry.
