Abstract

Two new μ3-oxo trinuclear heterometallic Fe2IIICrIII complexes with furan-2-carboxylic and salicylic acids with the composition: [Fe2CrO(C4H3OCOO)6(CH3OH)3]NO3·0.5CH3OH and [Fe2CrO(C6H4(OH)COO)7(CH3OH)2]·2DMA were synthesized starting from iron(III) and chromium(III) salts mixture. The complexes structures were confirmed by elemental analysis, IR, Mössbauer spectroscopies, and X-ray analysis. The atomic absorption spectroscopy confirmed that the iron: chromium ratio is 2:1. The thermal properties of both heteronuclear complexes have been investigated in oxidizing and inert atmospheres revealing the stability of the trinuclear core up to 170 and 220°C, respectively.

新型{Fe2CrO}异三核铁铬团簇的合成与表征

以铁(III)和铬(III)盐为原料，合成了两种新的μ3-氧杂金属Fe2IIICrIII与呋喃-2羧酸和水杨酸配合物，组成为[Fe2CrO(C4H3OCOO)6(CH3OH)3]NO3·0.5CH3OH和[Fe2CrO(C6H4(OH)COO)7(CH3OH)2]·2DMA。通过元素分析、红外光谱、Mössbauer光谱和x射线分析证实了配合物的结构。原子吸收光谱法证实铁铬比为2:1。在氧化和惰性气氛下研究了这两种异核配合物的热性质，揭示了三核核心分别在170和220°C下的稳定性。
