Aqua[1-(pyridin-2-yl)ethanone oximato][1-(2-pyridin-2-yl)ethanone oxime]copper(II) perchlorate monohydrate

B. Zhong, S. Li and G. Chen

Abstract: In the title compound, [Cu(C₇H₇N₂O)(C₇H₈N₂O)(H₂O)]ClO₄·H₂O, the Cu^II ion is five-coordinated by the N atoms from the 1-(pyridin-2-yl)ethanone oximate and 1-(pyridin-2-yl)ethanone oxime ligands and by the water O atom in a distorted square-pyramidal geometry. The two organic ligands are linked by an intramolecular O-HO hydrogen bond. In the crystal, molecules and ions are linked by O-HO hydrogen-bonding interactions, forming chains along the a axis. The perchlorate O atoms are disordered in a 0.58 (2):0.42 (2) ratio.
