title: Aqua-bis(1H-imidazole-κN)bis-(4-methyl-benzoato)-κO;κO,O'-nickel(II).
abstract: In the mononuclear title compound, [Ni(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)], the Ni(II) atom is coordinated by three carboxylate O atoms (from a bidentate 4-methyl-benzoate ligand and a monodentate 4-methyl-benzoate ligand), two N atoms (from two imidazole ligands) and a water mol-ecule in an octa-hedral geometry. Inter-molecular O-H⋯O hydrogen-bonding inter-actions lead to infinite chains, which are further self-assembled into a supra-molecular network through inter-molecular N-H⋯O hydrogen-bonding inter-actions and π-π stacking [centroid-centroid distance = 3.717 (2) Å].
