## Abstract The preparation of a family of dinuclear monocyclopentadienyl imidoniobium and ‐tantalum complexes was achieved by two different synthetic routes. The diimido complexes [{M(Cp′)Cl~2~}~2~(μ‐1,__i__‐NC~6~H~4~N)] [Cp′ = η^5^‐C~5~H~4~SiMe~3~, M = Nb, __i__ = 4 (1); Cp′ = η^5^‐C~5~H~4~SiMe~3

The reaction of [Cp\*MCl 4 ] (M ϭ Nb, Ta; Cp\* ϭ C 5 Me 5 ) with PH 2 R in toluene at room temperature gives the primary phosphine complexes [Cp\*MCl 4 (PH 2 R)] [Cp\* ϭ C 5 Me 5 ; M ϭ Nb: R ϭ Bu t (1a), Ad (2a), Cy (3a), Ph (4a), 2,4,6-Me 3 C 6 H 2 (Mes) (5a); M ϭ Ta: R ϭ Bu t (1b), Ad (2b), Cy (3b
