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

The title compound, [CuCl₂(C₇H₉N)₄], lies on a site of crystallographic 42 (D₄) 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) Å and the Cu-N distance is 2.0510 (12) Å. The space group of the Co analogue is revised from Pnnn to P4/­nnc.
