The synthesis of the first half-sandwich complexes based on the cyclononatetraenyl (Cnt = CH) ligand ([Ln(-Cnt)(-BH)(thf)] (Ln = La, Ce)) is reported. The title compounds were obtained from the reaction of [Ln(BH)(thf)] and [K(Cnt)]. Further solvation of [Ln(-Cnt)(-BH)(thf)] with tetrahydrofuran (THF) resulted in a reversible decoordination of the Cnt ring and the formation of the ionic species [Ln(-BH)(thf)][Cnt]. Removal of THF from [La(-Cnt)(-BH)(thf)] gave the polymeric compound [La(-BH)(-BH)(-Cnt)].
报道了基于环壬四烯基（Cnt = CH）配体的首个半夹心配合物的合成（[Ln(-Cnt)(-BH)(thf)]，Ln = La，Ce）。标题化合物由[Ln(BH)(thf)]与[K(Cnt)]反应制得。[Ln(-Cnt)(-BH)(thf)]进一步与四氢呋喃（THF）溶剂化导致Cnt环可逆解配位并形成离子物种[Ln(-BH)(thf)][Cnt]。从[La(-Cnt)(-BH)(thf)]中除去THF得到聚合物化合物[La(-BH)(-BH)(-Cnt)]。
