Heteroleptic actinocenes: a thorium(iv)-cyclobutadienyl-cyclooctatetraenyl-di-potassium-cyclooctatetraenyl complex.

ABSTRACT: Despite the vast array of η ⁿ -carbocyclic C_5-8 complexes reported for actinides, cyclobutadienyl (C₄) remain exceedingly rare, being restricted to six uranium examples. Here, overcoming the inherent challenges of installing highly reducing C₄-ligands onto actinides when using polar starting materials such as halides, we report that reaction of [Th(η⁸-C₈H₈)₂] with [K₂{C₄(SiMe₃)₄}] gives [{Th(η⁴-C₄[SiMe₃]₄)(μ-η⁸-C₈H₈)(μ-η²-C₈H₈)(K[C₆H₅Me]₂)}₂{K(C₆H₅Me)}{K}] (1), a new type o
