Abstract
The trinuclear copper(II) complexes [Cu3(OH)(pz)3(Hpz)2Cl2]·solv (Hpz = pyrazole, pz = pyrazolate anion, solv = H2O or tetrahydrofuran) have been obtained by oxidation reactions of [{Cu(Hpz)2Cl}2]. When treated with pyridine(py), both CuII derivatives gave the related compound [Cu3(OH)(pz)3(py)2Cl2]·py, which has been characterized by a single-crystal X-ray structure analysis. Crystals are orthorhombic, space group Pnma (no. 62), a = 19.883(3), b = 15.063(3), c = 9.495(2) Å, Z = 4, R = 0.035 and R′ = 0.041 for 1 472 absorption corrected reflections having I > 3σ(I).
