自1978年以来,取代环戊二烯基稀土配合物化学取得了较快的发展,这是由于具有较大体积的取代环戊二烯基可稳定低配位数的络合物,特别是可稳定单取代或双取代的环戊二烯基稀土氯化物。关于—C_5Me_5、—(Me_3Si)_2C_5H_3和桥联配体的稀土氯化物的合成已有不 Since 1978, the substitution of cyclopentadienyl rare earth complex chemistry has progressed rapidly due to the larger volume of substituted cyclopentadienyl-stable low coordination number complexes, especially Stably monosubstituted or disubstituted cyclopentadienyl rare earth chloride. The synthesis of rare earth chlorides with -C_5Me_5, - (Me_3Si) _2C_5H_3 and bridged ligands
