近年来含有稀土和过渡金属的金属有机化合物由于可能具有特殊的催化性能,因而引起了人们很大兴趣。对这类化合物的各种谱学研究和晶体结构测定得到稀土和过渡金属之间的不同连接方式。我们以二(五甲基环戊二烯基)氯化稀土与环戊二烯基羰基铁钠为原料合成了一系列含有稀土和铁的化合物,利用X光四圆衍射仪对其中之一测定晶体结构,并对其结构进行研究。
In recent years, metal-organic compounds containing rare earths and transition metals have drawn great interest because of the possible special catalytic properties. Various spectroscopic studies and crystal structure determinations of such compounds result in different linkages between rare earths and transition metals. A series of compounds containing rare earth and iron were synthesized from bis (pentamethylcyclopentadienyl) rare earth chloride and sodium cyclopentadienyl iron carbonyl. One of them was determined by X-ray diffractometry Crystal structure, and study its structure.
