title: Dichlorobis(2-chloro-5-methylpyridine-kappaN)copper(II).
abstract: In the crystals of the title compound, [CuCl(2)(C(6)H(6)ClN)(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) A, respectively. The two pyridine rings are parallel, but twist from the CuN(2)Cl(2) coordination plane by about 95 degrees in the complex molecule. There are three kinds of intermolecular C-H.Cl 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.
