Reaction of copper(I) chloride with the bidentate Schiff base N,N'-bis(trans-2-nitrocinnamaldehyde)ethylenediamine{Nca2en, systematic name (1E,1'E,2E,2'E)-N,N'-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]} in a 1:1 molarratio in dichloromethane without exclusion of air or moisture resulted in the formation of the title complex μ-hydroxido-μ-chlorido-bis[chlorido-{(1E,1'E,2E,2'E)-N,N'-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]-κ2N,N'}copper(II) as a dichloromethane sesquisolvate. The dinuclear complex has a folded four-membered ring in anunsymmetrical Cu2OCl3 core in which the approximate trigonal bipyramidal coordination displays different angulardistortions in the equatorial planes of the two copper(II) atoms; the chlorido bridge is asymmetric, but the hydroxidobridge is symmetric. The chelate rings of the two Nca2en ligands have different conformations, leading to a more markedbowing of one of the ligands compared with the other. This is the first reported dinuclear complex, and the first fivecoordinatecomplex, of the Schiff base ligand. Molecules are associated in pairs by ring-stacking interactions supportedby C—H···Cl interactions with solvent molecules; a further ring-stacking interaction exists between the two Schiff baseligands of each molecule.
