Diaqua(2,9-dimethyl-1,10-phenanthroline-κ2 N,N′)(3-hydroxybenzoato-κ2 O,O′)nickel(II) nitrate

Abstract

The asymmetric unit of the title compound, [Ni(C7H5O3)(C14H12N2)(H2O)2]NO3, comprises one half of the NiII complex cation and one half of the non-coordinated nitrate anion, as both the Ni atom and the N and one O atoms of the anion lie on twofold rotation axes. The Ni2+ cation is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand, two water molecules and a bidentate 3-hydroxybenzoate anion in a distorted octahedral environment. The OH group of the benzoate is disordered over two positions with equal occupancy. An extensive series of O—H...O hydrogen bonds leads to a supramolecular network structure.
