Chlorido1-(pyridin-2-yl)ethanone oximato-κ2 NN′1-(2-pyrid­yl)ethanone oxime-κ2 NN′copper(II) trihydrate

摘要

In the title compound, [Cu(C7H7N2O)Cl(C7H8N2O)]·3H2O, the metal 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 chloride anion in a distorted square-pyramidal geometry. The distortion parameter is 0.192. The two organic ligands are linked by an intra­molecular O—H⋯O hydrogen bond. In the crystal, mol­ecules are linked by O—H⋯O and O—H⋯Cl hydrogen bonds. The title compound is the hydrated form of a previously reported structure [Wu & Wu (2008). Acta Cryst. E>64, m828]. There are only slight variations in the mol­ecular geometries of the two compounds.
