## 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
