The first terbium (Tb)-monometallic cyanide clusterfullerene (CYCF), TbCN@C82, has been successfully synthesized and isolated, whose molecular structure was determined unambiguously as TbCN@C2(5)-C82 by single crystal X-ray diffraction. The C2(5)-C82 isomeric cage represents a new cage capable of encapsulating a monometallic cyanide cluster. The C-N bond length within the encaged TbCN cluster is determined to be 0.94(5) Å, which is smaller by at least 0.17 Å than those of the reported C-N triplet bonds in traditional cyanide/nitrile compounds and cyano coordination complexes. An electronic configuration of Tb(3+)(CN)(-)@C82 was proposed for TbCN@C82.
首个铽（Tb）单金属氰化物团簇富勒烯（CYCF），即TbCN@C82，已成功合成并分离出来，其分子结构通过单晶X射线衍射被明确确定为TbCN@C2(5)-C82。C2(5)-C82异构体笼代表一种能够包封单金属氰化物团簇的新笼。笼内TbCN团簇中的C-N键长被确定为0.94(5) Å，这比传统氰化物/腈类化合物和氰基配位络合物中报道的C-N三重键至少小0.17 Å。针对TbCN@C82提出了Tb(3+)(CN)(-)@C82的电子构型。
