| 摘要: 选择3种不同尺寸含氮配体（哌嗪、咪唑和三氮唑）与三羟甲基丙烷（H3tmp）和FeCl3采用溶剂热反应合成3例六核Fe（Ⅲ）合物：（C5H14N2）[Fe6（μ6-O）Cl6（tmp）4]·2H2O·CH3OH （1）、（C3H5N2）2[Fe6（μ6-O）Cl6（tmp）4] （2）和（C4H8N3）3（C2H4N3）[Fe12（μ6-O）2Cl12（tmp）8]·3CH3OH （3），并对它们的结构进行表征。发现三元醇配体有利于合成高核金属簇。3个化合物具有相同的阴离子簇[Fe6（μ6-O）Cl6（tmp）4]2-。通过晶体学参数，元素分析，红外等手段证实，在化合物1和3的体系中，氮杂环配体经历了N-和C-烷基化反应。 |

| Abstract: Solvothermal reactions of 1,1,1-tris(hydroxymethyl)propane (H3tmp) and FeCl3 by using different counter ions resulted in three hexanuclear iron(Ⅲ)clusters (C5N2H14)[Fe6(μ6-O)Cl6(tmp)4]·2H2O·CH3OH (1), (C3N2H5)2[Fe6(μ6- O)Cl6(tmp)4] (2), and (C4N3H8)3(C2N3H4)[Fe12(μ6-O)2Cl12(tmp)8]·3CH3OH (3), whose structures were characterized. The tripodal alcohols ligands are very useful in constructing high-nuclearity metal clusters. In all cases, similar anionic cluster[Fe6(μ6-O)Cl6(tmp)4]2- is formed by six Fe(Ⅲ)ions, four tmp3- ligands, one center O2- ion, and six Cl- ions. Within the system of compounds 1 and 3, the nitrogen-containing heterocyclic ligands experience N- and C-alkylation reactions, which is validated by the crystallographic parameters, elemental analyses, and IR. |
