摘要:An iron (III) cluster, namely [Fe10(μ3–O)8L8(NO3)6] (1), has been synthesized by treatment of Fe(NO3)3·9H2O with 3,5–dimethyl–1–(hydroxymethyl)–pyrazole (HL) under ambient temperature. The core skeleton of {FeIII 10} can be regarded as a pear-like cage with eight triangular {FeIII 3(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, {FeIII 10} 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 antiferromagnetic exchange behavior arising from the interactions between the iron(III) centers. © 2020
