摘要：

After obtaining a mononuclear complex [Cu(Hpz)(4)SO4](H2O) (1) (Hpz = pyrazole) through the reaction Of CuSO4.5H(2)O and pyrazole in water solution, we repeated the synthesis process in methanol solution and got an unexpected ID complex [Cu(Hpz)(4)SO4](n)(CH3OH)(n) (2), which has the same [Cu(Hpz)(4)SO4] unit but different coordination motif with 1. While we used Cu(ClO4)(2).6H(2)O in the synthesis system of 2, a rarely cyclic tri-nuclear copper(II) complex [Cu-3(mu(3)-O)(pz)(3)(Hpz)(3)(mu(1)mu(2)-ClO4)](CH3OH) (3) was obtained. The Cu-3(mut(3)-O)(pz)(3) unit in 3 consists of an almost flat Cu3N6 ring and a pyramidal Cu3O group with the average Cu-O distances of 1.998 Angstrom and the average Cu-O-Cu angle of 108degrees. Complexes 1-3 were characterized by X-ray structural analysis and ESR spectra. (C) 2004 Elsevier B.V. All rights reserved.
