of the Me 2 Si bridge and distortion of the sandwich structure facilitate the interaction of the 16‐electron ansa‐ complex (see picture; blue Ti, yellow Si, gray C) with σ‐donor/π‐acceptor ligands, such as CO or isocyanides, which allows the electronic structure of this strongly bent first ansa ‐cycloheptatrienyl–cyclopentadienyl transition‐metal complex to be studied. The complex is prepared from [(η‐C 7 H 7 )Ti(η‐C 5 H 5 )].
