Diaqua­(5-carb­oxy­benzene-1,3-di­carboxyl­ato-κO (1))(4,4′-dimethyl-2,2′-bipyridine-κ(2) N,N′)zinc

In the title compound, [Zn(C(9)H(4)O(6))(C(12)H(12)N(2))(H(2)O)(2)], the Zn(II) atom is five-coordinated by two N atoms from a 4,4′-dimethyl-2,2′-bipyridine ligand, one O atom from a 5-carb­oxy­benzene-1,3-dicarboxyl­ate ligand and two water mol­ecules in a distorted trigonal–bipyramidal geometry. The complex mol­ecules are linked by inter­molecular O—H⋯O hydrogen bonds and partly overlapping π–π inter­actions [centroid–centroid distance = 4.017 (2) Å] into a three-dimensional supra­molecular network.
