Abstract: In the polymeric title compound, [Cu3(C7H5O2)6(C11H9N3O)2]n, square-planar-coordinated CuII ions on crystallographic inversion centres are bound by two monodentate benzoate anions. The resulting [Cu(benzoate)]2 fragments are joined to centrosymmetic [Cu2(benzoate)4] paddlewheel clusters [CuCu = 2.6331 (5) Å] by means of bridging N-(pyridin-4-yl)nicotinamide (4-pna) ligands [dihedral angle between the aromatic rings = 39.18 (12)°], thereby forming [Cu3(benzoate)6(4-pna)2]n coordination-polymer chains that are arranged parallel to the [30-1] crystal direction. These polymeric chains are anchored into supramolecular layers by N-HO hydrogen bonding between neighboring 4-pna ligands. These layers aggregate by crystal packing forces to afford the crystal structure of the title compound.
