Aquabis(2-nitrobenzoato-kappaO)(1,10-phenanthroline-kappa2N,N')zinc(II).

: The title compound, [Zn(C7H4NO4)2(C12H8N2)(H2O)], 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) degrees].
