Crystal structure of μ(6)-chlorido-nona-kis-(μ-4-chloro-pyrazolato)bis-μ(3)-methoxo-hexa-copper(II).

The hexa-nuclear title compound, [{Cu(3)(μ(3)-OCH(3))(μ-C(3)H(2)ClN(2))(3)}(2)(μ-C(3)H(2)ClN(2))(3)(μ(6)-Cl)] or [Cu(6)(C(3)H(2)ClN(2))(9)(CH(3)O)(2)Cl], crystallizes in the space group Pbcn, with individual mol-ecules being located on a twofold rotation axis. The mol-ecule adopts a trigonal prismatic shape, with two trinuclear units linked by three 4-chloro-pyrazolate ligand bridges by encapsulating a Cl(-) anion in a μ(6)-coordination mode. In the crystal, individual mol-ecules are stacked into rods parallel to [1-10] that are arranged in a pseudo-hexa-gonal packing. Cohesion between mol-ecules is accomplished through weak C-H⋯Cl inter-actions.
