In the title compound, [Zn(C(6)H(6)N(4))(2)(H(2)O)(2)](C(16)H(8)O(8)), the Zn(II) atom, located on an inversion centre, is coordinated by two aqua and two bidentate biimidizole ligands, resulting in a slightly distorted octahedral ZnO(2)N(4) geometry. The four N atoms from the two biimidizole ligands lie in the equatorial plane and the two aqua O atoms lie in the axial sites. The biphenyltetracarboxylate anion also lies on an inversion centre. The Zn(II) complex cation and the anion are held together by N-H center dot center dot center dot O hydrogen bonds, forming a zigzag chain along [2 (1) over bar1]. The chains are further connected by water molecules via O-H center dot center dot center dot O hydrogen bonds.
