The products of the thermolysis of N ‐(1‐pyridinio)‐2‐nitroanilides ( 1 ) had previously been interpreted as tris (2‐nitrophenyl)‐triaziridines ( 3 ). The present work shows them to be actually 1, 2‐bis[( Z )‐(2′‐nitrophenyl)‐ONN‐azoxy]benzenes ( 5 ). The revised structural assignment is based on the chemical and the spectroscopic (especially 1 H‐NMR.) properties of 5 and on the results of a X‐ray structural analysis.
