Abstract

In the title compound, [CuCl(2)(C(9)H(8)N(2))(4)], there are two independent molecules in the asymmetric unit. The Cu(2+) ions lie on inversion centres and are octahedrally coordinated by two Cl atoms and four pyrazole N atoms. All pyrazole N-H groups form intramolecular hydrogen bonds, giving rise to five-membered hydrogen-bonded rings incorporating the Cu atoms.
