trans-tetraaquabis(pyridine-3-carboxylate-kappa N)-nickel(II)

Abstract

The title complex, [Ni(C6H4NO2)2(H2O)4], consists of an Ni atom coordinated to twotranspyridinecarboxylate ligands, coordinated through the N atoms, and four water ligands. The Ni atom lies on a site of 2/msymmetry, and the pyridinecarboxylate ligand lies on a mirror plane. Extensive inter-complex hydrogen bonding occurs between the water ligands and the carboxylate groups, resulting in a three-dimensional network.
