| Popis: |
In the title complex, [CuCl2(C9H12N4)], the CuII 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 CuII atom is essentially planar, with a maximum deviation of 0.0181 (17) A for one of the coordinated N atoms. This plane forms a dihedral angle of 30.75 (6)° with the CuCl2 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) A and a centroid–centroid distance of 3.581 (19) A. |
