title: Diaqua-bis(2-carboxy-benzoato-κO)nickel(II).
abstract: In the title compound, [Ni(C(8)H(5)O(4))(2)(H(2)O)(2)], the Ni(II) atom lies on an inversion centre and exhibits a square-planar geometry incorporating two phthalate and two water O atoms. The nickel complex is stabilized by intra-molecular inter-actions involving water O atoms and H atoms of the phthalate groups. It forms one-dimensional zigzag chains along the b axis which are held together via π-π stacking inter-actions (3.647 Å) between the benzene rings of the phthalate groups. The adjacent chains are also hydrogen bonded, resulting in a three-dimensional supra-molecular network.
