Tetraaquabis[4-(methylamino)benzoato-κO]nickel(II)

Abstract

The title complex, [Ni(C8H8NO2)2(H2O)4], is centrosymmetric with the NiII ion located on a centre of symmetry. It contains two 4-(methylamino)benzoate (PMAB) anions and four coordinated water molecules. The four O atoms in the equatorial plane around the NiII ion form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by two O atoms of the PMAB anions in the axial positions. In the crystal structure, intermolecular O—H...O, O—H...N, N—H...O and C—H...O hydrogen bonds link the molecules into a three-dimensional network.
