Abstract
The cyclobismuthanes R~n~Bi~n~, [R = 2‐(Me~2~NCH~2~)C~6~H~4~; n = 3 (1a), 4 (1b)] have been synthesised by reduction of RBiCl~2~ with Na in liquid NH~3~ or by reaction of R~2~BiCl with LiAlH~4~ in Et~2~O. The reaction of 1a/b with W(CO)~5~·THF afforded the bismuthinidene complex RBi[W(CO)~5~]~2~ (2). R~2~BiCl reacts with Mg in THF to give the dibismuthane R~4~Bi~2~ (3). Single‐crystal X‐ray structure analyses of 1b, 2, and 3 reveal intramolecular coordination of the pendant CH~2~NMe~2~ groups to the bismuth atom. (© Wiley‐VCH Verlag GmbH & Co.
