Abstract: The asymmetric unit of the title compound, [ZnCl₂(C₁₂H₁₂N₂)], contains two independent molecules. The Zn^II atoms are four-coordinated in distorted tetrahedral configurations by two N atoms from 5,5'-dimethyl-2,2'-bipyridine and two terminal Cl atoms. In the crystal structure, intermolecular C-HCl hydrogen bonds link the molecules. There are C-H [pi] contacts between the methyl groups and the pyridine and five-membered rings containing Zn^II atoms; [pi] - [pi] contacts also exist between the pyridine rings [centroid-centroid distances = 3.665 (5) and 3.674 (5) Å].
