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. Mol-ecules of the CuII complex are connected via C-H⋯O hydrogen bonds involving the nitro and keto oxygen atoms, thus forming supra-molecular networks. Mol-ecules of the aryl-hydrazone component are linked by C-H⋯O inter-actions into zigzag strands showing no inter-strand association.

Keywords: CuII chelate; C—H⋯O hydrogen bonding; aryl­hydrazone; crystal structure; mol­ecular layer formation; two-component crystal.
