and its neutral precursor (η-C5H5)Mo(CO)(N2C6H4CH3-p)(PPh3) (VIII)_have been characterised by X-ray crystallographic methods. Crystals of [VIIf]PF6 are triclinic, space group P with two molecules in a unit cell of dimensions a = 13.031(4), b = 14.413(4), c = 11.140(5) Å and α = 93.17(3), β = 104.73(3), and γ = 115.77(3)°. Crystals of VIII are monoclinic, space group P21/c with four molecules in a unit
