(μ-3-Acetyl-5-carboxyl-ato-4-methyl-pyrazolido-1:2κN,O:N,O)-μ-chlorido-tetra-pyridine-1κN,2κN-chlorido-1κCl-dicopper(II) propan-2-ol solvate.

The title compound, [Cu(2)(C(7)H(6)N(2)O(3))Cl(2)(C(5)H(5)N)(4)]·C(3)H(8)O, is a binuclear pyrazolate complex, in which the two Cu(II) atoms have different coordination numbers and are connected by a bridging Cl atom. One Cu(II) atom has a distorted square-pyramidal coordination environment formed by two pyridine N atoms, one bridging Cl atom and an N,O-chelating pyrazolate ligand. The other Cu(II) atom adopts an octa-hedral geometry defined by two pyridine N atoms at the axial positions, two Cl atoms and the coordinated pyrazolate ligand in the equatorial plane. An O-H⋯O hydrogen bond connects the complex mol-ecules and propan-2-ol solvent mol-ecules into pairs. These pairs form columns along the a axis.
