Di-μ-nicotinamide-κO:N;κN:O-bis-[aqua-bis-(4-meth-oxy-benzoato-κO)copper(II)].

ABSTRACT: The asymmetric unit of the centrosymmetric dinuclear title compound, [Cu(2)(C(8)H(7)O(3))(4)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], contains one half of the complex mol-ecule. Each Cu(II) atom is five-coordinated by one N atom from one bridging nicotinamide ligand and one O atom from another symmetry-related bridging nicotinamide ligand, two O atoms from two 4-meth-oxy-benzoate ligands, and one water mol-ecule, forming a distorted square-pyramidal geometry. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into layers parallel to (01). π-π inter-actions, indicated by short inter-molecular distances of 3.801 (1) Å between the centroids of the benzene rings and 3.653 (1) Å between the centroids of the pyridine rings, further stabilize the structure.
