The structures of CpV(O)Cl2, [CpV(N)Cl2], and Cp*V(O)Cl2 all display significant ring-slippage. This is evidenced by both elongated V–C bond lengths for the carbon atoms located trans to the oxo or nitrido ligands, as well as asymmetric C–C distances within the cyclopentadienyl ring. Herein, we compare the crystal structures of these complexes with their optimum geometries as predicted by DFT calculations. Our results indicate that these complexes should properly be regarded as formally 14–electron species, namely: (η3-C5H5)V(O)Cl2, [(η3-C5H5)V(N)Cl2], and (η3-C5Me5)V(O)Cl2.
