Aquabis(3-pyridylacrylato)-kappa O-2,O '; kappa O-bis(3-pyridylmethanol-kappa N)copper(II)

In the title complex, [Cu(C8H6NO2)(2)(C6H7NO)(2)(H2O)], the Cu2+ ion has a highly distorted square-bipyramidal (4 + 1 + 1) coordination environment, and is bonded to three carboxylate O atoms of two 3-pyridylacrylate anions (monodentate and asymetric bidentate), two pyridine N atoms of 3-pyridyl-methanol ligands and one water O atom. O-(HO)-O-... and O-(HN)-N-... hydrogen bonds result in the formation of a two-dimensional layer structure.
