Hexa-μ2-chlorido-μ4-oxido-tetrakis[(morpholine-κN)copper(II)] methanol disolvate

Abstract

In the title solvate, [Cu4(μ2-Cl)6(μ4-O)(C4H9NO)4]·2CH3OH, each Cu2+ ion in the tetranuclear complex has a trigonal–bipyramidal coordination arising from three bridging chloride ions in equatorial positions and the central μ4-O2− ion and morpholine N atom in axial positions. The morpholine rings adopt chair conformations, with the N—Cu bonds in equatorial orientations. In the crystal, the components are linked by N—H...O and O—H...O and O—H...Cl hydrogen bonds, which generate a three-dimensional network. One methanol molecule is disordered over two sets of sites in a 0.642 (9):0.358 (9) ratio.
