Bis(pyridine-2,3-dicarboxylato-N,O)copper(II)

The coordination geometry of the Cu atom in the title compound, [Cu(C₇H₅NO₄)₂], is distorted octahedral and the molecule displays crystallographic inversion symmetry. The Cu atom is bonded to a carboxylate O atom (at the pyridine 2-position) and the pyridine N atom of two ligands, the four atoms forming the equatorial plane, and via weaker axial contacts to two carboxylic acid O atoms (at the pyridine 3-position) of adjacent molecules. Strands of molecules are thus linked parallel to the x axis and hydrogen bonds link the strands parallel to the y axis.
