Highly symmetrical arrangements of the lanthanide metals Ln including the S -symmetrical chair conformations of the [Sm(CN)] ring in 1 or an icosahedron as in 2 (see picture) are found in novel multinuclear cyclopentadienyl complexes. The formation of different structural motifs is directed by ionic bonding criteria such as the nature of the bridging heteroligands and the Cp/Ln ratio. [{(C Me ) Sm(µ-CN)} ] 1 [(C Me ) Sm (µ -Cl) ] 2.
在新型多核环戊二烯基配合物中发现了镧系金属Ln的高度对称排列，包括1中[Sm(CN)]环的S-对称椅式构象或2中的二十面体（见图）。不同结构基序的形成由离子键标准引导，如桥连杂配体的性质和Cp/Ln比率。[{(CMe)Sm(µ-CN)}] 1 [(CMe)Sm(µ-Cl)] 2 。
