Dichlorido(3,5,5′-trimethyl-1,3′-bi-1H-pyrazole-κ(2) N (2),N (2′))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) Å 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 mol­ecules is linked into a centrosymmetric dimer by N—H⋯Cl hydrogen bonds. The crystal structure is stabilized by inter­molecular C—H⋯N and C—H⋯Cl hydrogen bonds and weak slipped π–π stacking inter­actions between symmetry-related mol­ecules, with an inter­planar separation of 3.439 (19) Å and a centroid–centroid distance of 3.581 (19) Å.
