制备了二茂铁配合物[Fe(dppFc)2](BF4)2·2Et2O(1·2Et2O, dppFc = 1-二茂铁-2-{（2,6-二（吡唑基）吡啶基}乙烯）。x射线晶体学分析表明，随着晶体溶剂分子的释放，1·2Et2O发生了单晶到单晶的转变。在磁化率测量中，观察到溶剂分子诱导的顺磁性和自旋交叉之间的可逆转换。
An iron(II) complex with ferrocenyl groups, [Fe(dppFc)2](BF4)2·2Et2O (1·2Et2O, dppFc = 1-ferrocenyl-2-{(2,6-bis(pyrazolyl)pyridyl}ethylene), was prepared. X-ray crystallographic analyses revealed that 1·2Et2O underwent a single-crystal-to-single-crystal transformation with the release of crystal solvent molecules. In magnetic susceptibility measurements, a reversible conversion between paramagnetism and spin-crossover induced by solvent molecules was observed.
