Not only mononuclear complexes having a single pentalene or methylpentalene ligand but also homoleptic complexes with two η 8 ‐C 8 H 6 or η 8 ‐C 8 H 5 CH 3 ligands can be formed by titanium, zirconium, and hafnium. The syntheses, which start from the corresponding metallocene dihalides, are particularly simple. The homoleptic pentalene complex 1 reacts with [ZrCl 4 (thf) 2 ] to form the dichloro complex 2 , the first mononuclear “half‐sandwich” complex having a pentalene ligand.
