Multiple Bonds between Main‐Group Elements and Transition Metals, CII [1] . — Volatile MN 4 Metal Complexes of Niobium and Tantalum Containing Dimethylsilyl Substituents Niobium and tantalum complexes 4a and 4b of formula (Me 2 SiH)N=M[N(SiHMe 2 ) 2 ] 3 ( a : M=Nb; b : M=Ta) are formed from lithium bis(dimethylsilyl)amide and either MOCl 3 ( 2a , b ) or MCl 5 ( 3a , b ). No β‐hydrogen decomposition of these compounds occurs under normal conditions.
