Multiple Bonds Between Main‐Group Elements and Transition Metals, XCVI. – Niobium and Tantalum Complexes Having Imido Ligands The new niobium and tantalum complexes 2b and 2c of formula M[N(SiMe 3 ) 2 ] 2 (NSiMe 3 )(OSiMe 3 ) (M = Nb, b ; Ta, c) are accessible by the reaction of the oxychlorides MOCl 3 with the lithium amide LiN[Si(CH 3 ) 3 ] 2 in 36 and 27% isolated yield, respectively.
