title: Tetra-kis[tris-(2,2'-bi-1H-benzimidazole)nickel(II)] bis-(phosphate) sulfate.
abstract: The title compound, [Ni(C(14)H(10)N(4))(3)](4)(PO(4))(2)(SO(4)), consists of [Ni(C(14)H(10)N(4))(3)](2+) complex cations (.3. symmetry) and disordered anions ( symmetry) with occupancy factors of two-thirds for PO(4) (3-) and one-third for SO(4) (2-). The Ni(2+) centre is chelated by three bidentate 2,2'-bi-1H-benzimidazole mol-ecules in a distorted octa-hedral coordination. N-H⋯O hydrogen bonds consolidate the building units into a framework structure.
