Abstract: The title compound, [Cu₂(C₇H₆N₂O₃)Cl₂(C₅H₅N)₄]·C₃H₈O, 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 octahedral 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-HO hydrogen bond connects the complex molecules and propan-2-ol solvent molecules into pairs. These pairs form columns along the a axis.
