The coordination chemistry of a ferrocene ligand with one bulky amidinate function attached to each ring toward two different coinage metal precursors was investigated. In dependence of the metal and the co-ligands, "ansa" type structures and non-bridged structures were obtained. Six different compounds are reported. In the "ansa" type structures, short Fe-M (M = Cu, Ag) distances were observed in the molecular structures in the solid state. However, theoretical calculations (DFT) did not reveal a stabilizing metal-metal interaction. Instead, dispersion interactions within the ligand and between the ligand and metal seem to represent the main stabilization forces.
研究了一种二茂铁配体的配位化学，该配体的每个环上都连接有一个庞大的脒基官能团，使其与两种不同的货币金属前体发生作用。根据金属和共配体的不同，得到了“ansa”型结构和非桥连结构。报道了六种不同的化合物。在“ansa”型结构中，固态分子结构中观察到较短的Fe-M（M = Cu，Ag）距离。然而，理论计算（DFT）并未揭示稳定的金属-金属相互作用。相反，配体内以及配体与金属之间的色散相互作用似乎是主要的稳定作用力。
