title: Diaqua-bis(2,2'-bi-1H-imidazole-κN,N)nickel(II) bis-(3-methyl-benzoate) 3-methyl-benzoic acid disolvate.
abstract: 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 ) is coordinated by two N,N'-bidentate 2,2'-biimidazole ligands and two water mol-ecules, 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 mol-ecule is disordered over two sites in a 0.563 (17):0.437 (17) ratio.
