The preparation of [3]thoro‐ and [3]uranocenophanes, the first structurally authenticated ansa ‐bridged complexes of actinocenes, is reported. Following a flytrap route, 1,2‐bis(cyclooctatetraenyldimethylsilyl)methane was synthesized, reduced to its tetraanion, and subsequently converted into bridged uranocene and thorocene complexes by salt metathesis with the corresponding actinide tetrachlorides. In addition, their electronic structures have been investigated by experimental (UV/Vis spectroscopy, cyclic voltammetry) and theoretical (DFT) methods.
