The new niobium- and tantalum complexes 3a and 3b of formula (M = Nb, a; Ta, b) are accessible by the reaction of the oxychlorides MOCl3 with the lithium amide (2) in 30 and 19percent isolated yield, resp.The new silazanes cyclo2 (5) and cyclo-3 (6) are prepared from (CH3)2ClSiCH2CH2SiCl(CH3)2 and NH3.Their structures - ten- and fifteeen-membered rings - were determined by single-crystal structure analyses.
