Bis(methanol-κO)bis(1,2-diamino-2-hydroxyiminoethanone oximato-κ2N,N′)copper(II) bis(oxamide dioxime) methanol disolvate

Abstract

In the title compound, [Cu(C2H5N4O2)2(CH3OH)2]·2C2H6N4O2·2CH3OH, the CuII atom, lying on an inversion center, is coordinated by four N atoms from two 1,2-diamino-2-hydroxyiminoethanone oximate anion and two O atoms from two methanol molecules in a distorted octahedral geometry. The two uncoordinating oxamide dioxime molecules, each lying on an inversion center, adopt a trans conformation. In the crystal, O—H...O, N—H...O and N—H...N hydrogen bonds link the complex molecules and the oxamide dioxime and methanol molecules.
