The asymmetric unit of the title compound, [Zn(C12H12N2)(H2O)4]SO4, consists of a ZnII complex cation, a sulfate anion and four molecules of water coordinated to the ZnII atom. The ZnII complex cation, with approximate twofold symmetry, displays a slightly distorted octahedral geometry around the ZnII atom, which is coordinated by two N atoms from a 5,5′-dimethyl-2,2′-bipyridine ligand and by the O atoms of four water molecules. In the crystal, O—H⋯O hydrogen bonds help to establish the packing.
