摘要：

In the polymeric title compound, [Cu-3(C7H5O2)(6)(-) (C11H9N3O)(2)](n), square-planar-coordinated Cu-II ions on crystallographic inversion centres are bound by two monodentate benzoate anions. The resulting [Cu(benzoate)](2) fragments are joined to centrosymmetic [Cu-2(benzoate)(4)] paddlewheel clusters [Cu center dot center dot center dot Cu = 2.6331 (5) angstrom] by means of bridging N-(pyridin-4-yl) nicotinamide (4-pna) ligands [dihedral angle between the aromatic rings = 39.18 (12)degrees], thereby forming [Cu-3(benzoate)(6)(4-pna)(2)](n) coordination-polymer chains that are arranged parallel to the [30 (1) over bar] crystal direction. These polymeric chains are anchored into supramolecular layers by N-H center dot center dot center dot O hydrogen bonding between neighboring 4-pna ligands. These layers aggregate by crystal packing forces to afford the crystal structure of the title compound.
