Short summary
A rigid and bulky organobismuthinidene (1) reacts with organic azides to form unprecedented, unsupported iminobismuthane (2) with the shortest reported Bi–N distance (2.041(3) Å), and the first tetraazabismole (BiN4) heterocycle (3).

Key points
- A monocoordinate bismuthinidene (1) was synthesized and reacted with organic azides.
- The reaction with p-toluenesulfonyl azide produced an unsupported iminobismuthane (2) with a Bi–N bond length of 2.041(3) Å, the shortest reported.
- Reaction with 4-azidobiphenyl yielded the first tetraazabismole (BiN4) heterocycle (3).
- The bismuthinidene (1) demonstrated catalytic activity in the reduction of organic azides.

Abstract
ABSTRACT Herein, we report the reactivity of a monocoordinate bismuthinidene ( 1 ) with various organic azides. The reaction of 1 with p ‐toluenesulfonyl azide resulted in the formation of an unprecedented, unsupported iminobismuthane ( 2 ), which features the shortest reported Bi–N distance of 2.041(3) Å in an iminobismuthane. Conversely, the reaction of 1 with 4‐azidobiphenyl resulted in the first example of a species containing a tetraazabismole (BiN 4 ) heterocycle ( 3 ). We also highlight that 1 demonstrates catalytic activity, enabling the reduction of a selection of organic azides.
