Bis(methanol-κO)bis-(1,2-diamino-2-hy-droxy-imino-ethanone oximato-κ(2)N,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.
