摘要
An iron(Ⅲ) cluster,namely [Fe10(μ3-O)8L8(NO3)6](1),has been synthesized by treatment of Fe(NO3)3·9 H2O with 3,5-dimethyl-l-(hydroxymethyl)-pyrazole(HL) under ambient temperature.The core skeleton of {FeⅢ10) can be regarded as a pear-like cage with eight triangular {FeⅢ3(μ3-O)} units,in which each three FeⅢ centers is held together by one μ3-O2- group with FeⅢ centers as corner-sharing triangle units.Importantly,{FeⅢ10} cluster is not only stable in solid state but also in solution,which is confirmed by powder X-ray diffraction(PXRD) pattern and electrospray ionization mass spectrometry(ESI-MS),respectively.Furthermore,1 shows anti ferromagnetic exchange behavior arising from the interactions between the iron(Ⅲ) centers.
