Di-Μ-Nicotinamide-Κ2O:N1;Κ2N 1:O-Bis­[Aqua­Bis­(4-Meth­Oxy­Benzoato-Κo)Copper(Ii)]

Abstract

The asymmetric unit of the centrosymmetric dinuclear title compound, [Cu2(C8H7O3)4(C6H6N2O)2(H2O)2], contains one half of the complex mol­ecule. Each CuII 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-meth­oxy­benzoate ligands, and one water mol­ecule, forming a distorted square-pyramidal geometry. Inter­molecular O—H⋯O and N—H⋯O hydrogen bonds link the mol­ecules into layers parallel to (01). π–π inter­actions, indicated by short inter­molecular 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.
