Crystal structure of [mu]6-chlorido-nona­kis­([mu]-4-chloro­pyrazolato)bis-[mu]3-methoxo-hexa­copper(II)

The hexa­nuclear title compound, [{Cu₃(₃-OCH₃)(-C₃H₂ClN₂)₃}₂(-C₃H₂ClN₂)₃(₆-Cl)] or [Cu₆(C₃H₂ClN₂)₉(CH₃O)₂Cl], crystallizes in the space group Pbcn, with individual mol­ecules being located on a twofold rotation axis. The mol­ecule adopts a trigonal prismatic shape, with two trinuclear units linked by three 4-chloro­pyrazolate ligand bridges by encapsulating a Cl^- anion in a ₆-coordination mode. In the crystal, individual mol­ecules are stacked into rods parallel to [1-10] that are arranged in a pseudo-hexa­gonal packing. Cohesion between mol­ecules is accomplished through weak C-HCl inter­actions.
