Sm(TpMe2)2(1)与Hg(C⋮CPH)2在四氢呋喃中于常温下反应，得到了无碱的稀土络合物(TpMe2)2Sm(C⋮CPH)(2)。2在苯中热分解生成新的配合物(TpMe2){Hb(Me2pz)2(C⋮Cph)}Sm(Me2pz)(3)，这是Sm(III)中心有趣的、不寻常的配体重排的结果。配合物2和3已用光谱分析和X-射线结晶学进行了充分表征。
Reaction of Sm(TpMe2)2 (1) with Hg(C⋮CPh)2 in THF at ambient temperature afforded the monomeric, base-free lanthanide alkynide complex (TpMe2)2Sm(C⋮CPh) (2). Thermolysis of 2 in benzene resulted in clean transformation to the new complex (TpMe2){HB(Me2pz)2(C⋮CPh)}Sm(Me2pz) (3), the result of an interesting, unusual ligand rearrangement on the Sm(III) center. Complexes 2 and 3 have been fully characterized by spectroscopic methods and X-ray crystallography.
