silicon-containing dicarboxylic acids were used to prepare two new heterotrinuclear carboxylates of the composition [Fe2IIICoIIO(Bcpdps)3(H2O)3], I , where H2Bcpdps ≡ HOOC-C6H4-Si(C6H5)2-C6H4COOH, and [Fe2IIICoIIO(Ipds)3(H2O)3], II , where H2Ipds ≡ [HOOC-C6H3(CO)2N-(CH2)3-(CH3)2Si]2O. The precursor for these two complexes was trinuclear µ3-oxo-hexaacetate triaqua diiron(III)cobalt(II) cluster, Fe 2 CoO}
含硅二元羧酸首次用于制备两种新的[Fe 2 III Co II O(Bcpdps)3(H 2 O)3 ], I的 杂三核羧酸盐,其中H 2 Bcpdps≡HOOC-C 6 H 4 -Si(C 6 H 5)2 -C 6 H 4 COOH和[Fe 2 III Co II O(Ipds)3(H 2 O)3 ], II ,其中H 2IPDS≡[HOOC-C 6 H ^ 3(CO)2 N-(CH 2)3 - (CH 3)2的Si] 2 O.这两个复合物的前体是三核μ 3 -氧代-六乙酸酯triaqua二铁(III)钴(II)簇, Fe 2 CoO} ,其中乙酸根阴离子随后被含硅的阴离子取代。通过元素分析,热重分析,傅立叶变换红外(FTIR),能量色散X射线荧光(EDXRF)和Mossbauer光谱(MS)对所得产物进行表征。MS的调查显示,存在高自旋态且环境紧密的铁(3+)离子。热重分析结果表明,
