Dichlorido(3,5,5'-trimethyl-1,3'-bi-1H-pyrazole-κN,N)copper(II).

In the title complex, [CuCl(2)(C(9)H(12)N(4))], the Cu(II) atom exhibits a distorted square-planar coordination geometry involving two chloride ions and two N-atom donors from the bipyrazole ligand. The chelate ring including the Cu(II) atom is essentially planar, with a maximum deviation of 0.0181†(17)†à for one of the coordinated N atoms. This plane forms a dihedral angle of 30.75†(6)° with the CuCl(2) plane. In the crystal, each pair of adjacent mol-ecules is linked into a centrosymmetric dimer by N-H⋯Cl hydrogen bonds. The crystal structure is stabilized by inter-molecular C-H⋯N and C-H⋯Cl hydrogen bonds and weak slipped π-π stacking inter-actions between symmetry-related mol-ecules, with an inter-planar separation of 3.439†(19)†à and a centroid-centroid distance of 3.581†(19)†à .
