文摘

A new copper(II) complex with chloride bridges and mixed blocking ligands, [{Cu(pz^Ph)(Opo)}₂(μ-Cl)₂] (1), whereby pz^Ph = 3-phenyl-pyrazolyl, and OpoH = 2-hydroxypyridine-N-oxide, has been obtained by degrading tris(pyrazolyl)borate in the presence of hydrated CuCl₂ salt and the ligand Opo⁻. The molecular structure of 1 was solved by X-ray diffraction. The two Cu(II) atoms of the dinuclear complex have a pyramidal arrangement in which the two pyramids share one base-to-apex edge with parallel basal planes. Magnetic susceptibility measurements revealed ferromagnetic coupling between the Cu atoms, with J = +8.72 cm⁻¹. X-band EPR spectra of CH₂Cl₂ solutions of 1 were recorded at different temperatures.
