Abstract

Multiple Bonds Between Main–Group Elements and Transition Metals, CXX¹. – Niobium and Tantalum Amide Complexes and New Cyclocarbodisilazanes The new niobium‐ and tantalum complexes 3a and 3b of formula [(CH₃)₂ are accesible by the reaction of the oxychlorides MOCl₃ with the lithium amide (2) in 30 and 19% isolated yield, resp. The new silazanes cyclo‐[(CH₃)₂Si(CH₂)₂Si(CH₃)₂NH]₂ (5) and cyclo‐[(CH₃)₂Si(CH₂)₂Si‐(CH₃)₂NH]₃ (6) are prepared from (CH₃)₂ClSiCH₂CH₂Si–Cl(CH₃)₂ and NH₃. Their structures – ten‐ and fifteen–membered rings – were determined by single–crystal structure analyses.
