Aquabis(2-nitrobenzoato-κO)(1,10-phenanthroline-κ2N, N')zinc(II)

The title compound, [Zn(C 7 H 4 NO 4 ) 2 (C 12 H 8 N 2 )(H 2 O)], has been synthesized. X-Ray analysis reveals that it is a neutral zinc(II) mononuclear carboxylate complex based on mixed N-and O-donor ligands. The Zn atom is five-coordinate in a distorted trigonal-bipyramidal coordination environment involving two O atoms of two monodentate 2-nitrobenzoate molecules, two N atoms of a 1,10-phenanthroline molecule and one O atom of a water molecule. The axial positions are occupied by a carboxylate O atom from the 2-nitrobenzoate ligand and an N atom from the 1,10-phenanthroline ligand [N-Zn-O = 167.66 (9)°].
