The ligand exchange MX5 . L + \*L 8 MX, . \*L + L for the octahedral adducts MX, . L, in an inert solvent (CH2CI2 or CHCI,) with neutral ligands, proceeds via a dissociative D mechanism when M = Nb, X = C1 and L= phosphoryl compound. A dissociative interchange Id mechanism is suggested when M = N b
