Crystal structure of (N,N′-ethylenebis{3-[2-(3-nitrophenyl)hydrazin-1-ylidene]-4-oxopentan-2-iminato})copper(II)–3-[2-(3-nitrophenyl)hydrazin-1-ylidene]pentane-2,4-dione (1/1)

Abstract

In the title 1:1 co-crystal, [Cu(C24H24N8O6)]·C11H11N3O4, each of the crystal components forms undulating layers which stack alternately along the b-axis direction. Molecules of the CuII complex are connected via C—H...O hydrogen bonds involving the nitro and keto oxygen atoms, thus forming supramolecular networks. Molecules of the arylhydrazone component are linked by C—H...O interactions into zigzag strands showing no interstrand association.
