trans-Dichloridotetrakis(3,5-dimethylpyridine)copper(II).

The title compound, [CuCl(2)(C(7)H(9)N)(4)], lies on a site of crystallographic 42 (D(4)) symmetry in the space group P4/nnc, and is isomorphous with the Ni and Co analogues. The Cu and Cl atoms thus lie on a fourfold axis, and the 3,5-lutidine ligands lie on twofold axes. The Cu-Cl distance is 2.7649 (7) A and the Cu-N distance is 2.0510 (12) A. The space group of the Co analogue is revised from Pnnn to P4/nnc.
