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.
