Treatment of the tris(cyclopentadienyl) cation ( 1 + ) with zirconocene dichloride 2 gave, in almost quantitative yield, the 1:1 adduct 7 + , which was isolated with [(CH 3 )B(C 6 F 5 ) 3 ] − as the counterion. Reaction of 1 + with the organometallic ligand Cp 3 ZrCl afforded the 1:1 adduct 8 + , again isolated with [(CH 3 )B(C 6 F 5 ) 3 ] − . The X‐ray analysis revealed that 7 + displays a strongly bent Zr−Cl−Zr coordination mode, in contrast to 8 + , which has a tendency to linear coordination. A theoretical analysis suggests that a subtle balance between steric and electronic factors determines the geometries in such organometallic adducts.
