A reaction of [Cu(pzH)4(NO3)2] (pzH = pyrazole) (1) with 2 equiv of Cu(NO3)2·3H2O at pH 6 afforded the unusual hexacopper(II) complex [Cu3(μ3-OH)(μ-pz)3(μ4-NO3)(pzH)3]2(μ-NO3)2 (pz = pyrazolate) (2). Both 1 and 2 have been structurally characterized by X-ray diffraction. The intertrimer linkage in 2 is supported with two bridging nitrate ions. The behavior of 2 in aqueous media has been examined by means of electronic absorption spectroscopy and electric conductivity measurements.
