Diaqua­bis(2,2′-bi-1H-imidazole-κ(2) N (3),N (3′))nickel(II) bis­(3-methyl­benzoate) 3-methyl­benzoic acid disolvate

In the title compound, [Ni(C(6)H(6)N(4))(2)(H(2)O)(2)](C(8)H(7)O(2))(2)·2C(8)H(8)O(2), the Ni(II) atom (site symmetry [Image: see text]) is coordinated by two N,N′-bidentate 2,2′-biimidazole ligands and two water mol­ecules, resulting in a slightly distorted trans-NiO(2)N(4) geometry for the metal ion. In the crystal, the components are linked by N—H⋯O and O—H⋯O hydrogen bonds, generating an infinite two-dimensional network running parallel to (100). The methyl group of the benzoic acid mol­ecule is disordered over two sites in a 0.563 (17):0.437 (17) ratio.
