Abstract
In the hydrated complex tetrakis(μ-2-carboxy-6-nitrobenzoato-κ 2 O : O ′)bis(μ-3-nitrobenzene-1,2-dicarboxylato-κ 2 O : O ′)tetrakis[(1,10-phenanthroline-κ N : N ′)copper(II)] hexahydrate, [Cu 4 (C 8 H 4 NO 6 ) 4 (C 8 H 3 NO 6 ) 2 (C 12 H 8 N 2 ) 4 ]·6H 2 O, the Cu II centres exhibit distorted coordination geometries defined by nitrogen atoms from chelating 1,10-phenanthroline ligands and oxygen atoms from 3-nitrophthalate anions. The centrosymmetric molecular assembly is consolidated by bridging carboxylate groups, while the crystal packing is governed by hydrogen bonding and π–π stacking interactions between aromatic rings. The scattering contribution of one disordered water molecule contribution was treated using the SQUEEZE procedure.
