Abstract: In the crystals of the title compound, [CuCl₂(C₆H₆ClN)₂], the Cu atom lies on an inversion centre and is four-coordinated by two pyridine N atoms and two Cl atoms in trans positions. The coordination geometry is square planar, with Cu-N and Cu-Cl distances of 1.986 (2) and 2.2536 (11) Å, respectively. The two pyridine rings are parallel, but twist from the CuN₂Cl₂ coordination plane by about 95° in the complex molecule. There are three kinds of intermolecular C-HCl hydrogen bonds in the crystals. Two of these types generate two-dimensional molecular networks, viewed in the direction of the a axis, and the other connects adjacent molecular networks.

Formula: [CuCl₂(C₆H₆ClN)₂]
