AsIII and SbIII ligands, L1 with [Fe3(CO)12] under mild conditions give [Fe3CO11(L)], [Fe3CO10(L)2], and [Fe3(CO)9P(OR)3}3] derivatives as well as the mono- nuclear [Fe(CO)4(L)] and [Fe(CO)32] complexes. Cluster breakdown is greatest with phosphines and least with phosphites. Of the compounds thus obtained, only [Fe3(CO)9 P(OR)33}3] (R = iPr, cyclo-C6H11 and, perhaps, Et, o-MeC64 and p-MeC6H4) exist solely
各种p III,As III和Sb III配体L 1与[Fe 3(CO)12 ]在温和条件下的反应得到[Fe 3 CO 11(L)],[Fe 3 CO 10(L)2 ],和[Fe 3(CO)9 P(OR)3 } 3 ]衍生物以及单核[Fe(CO)4(L)]和[Fe(CO)3 2 ]配合物。膦类的团簇分解最大,而亚磷酸盐的团簇分解最少。在如此获得的化合物中,只有[Fe 3(CO)9 P(OR)3 3 } 3 ](R = i Pr,环-C 6 H 11,也许还有Et,o -MeC 6 4和p -MeC 6 H 4)仅作为非桥联异构体存在于固态以及溶液中。其余为固态的CO桥连物种,其结构可能基于[Fe 3(CO)12]的CO桥连形式。]。在溶液中,它们异构化为CO桥联异构体与其他不具有桥联配体的混合物。后者占主导地位。非桥接互变异构体的红外光谱不能得出关于其结构的任何结论。
