摘要：

The reactions of 3,5-bis(trifluoromethyl)pyrazole ((CF3)(2)PzH) with the binuclear complex [Phen(2)Co(2)(mu-OH2)(mu-OOCMe)(2)(OOCMe)(2)] were studied. The reaction in dichloromethane under mild conditions gave the complex [Co-2(Phen)(2)(mu-H2O)(mu-OOCMe)(2)(OOCMe)(2)]((CF3)(2)PzH)(4) (I). Refluxing of I in ortho-xylene resulted in deprotonation of pyrazole giving two mononuclear complexes: pyrazolate [Co(Phen)(2)(H2O)(OOCMe)]((CF3)(2)Pz) (II) and pyrazolate acetate [Co(Phen)(2)((CF3)(2)Pz)(2)] (III). Compounds I-III were studied by X-ray diffraction (CCDC nos. 2159355-2159357), IR spectroscopy, and elemental analysis. The thermal behavior of I was investigated by TGA.
