An o-nitro-O-Aryl oxime was observed to exhibit a short O?O contact, which exhibited characteristics consistent with a chalcogen bond. The O-N bond length of the oxime was appreciably longer than the expected value, and NBO calculations indicated the presence of a n(O) → (O-N) orbital delocalisation. Topological analysis of the experimental electron density of two analogues shows the presence of a bond path between the two oxygen atoms, with (r) and 2(r) values consistent with an electrostatic interaction. Finally, electrostatic potential calculations indicate the presence of a-hole, the smoking gun indicating a Ch-bond. These results are unusual as oxygen is not typically considered to be a Ch-bond donor, especially in unactivated systems such as oximes.

The reaction of aryl diazonium salts containing electron-withdrawing substituents in the aromatic ring with acetone oxime leads to the formation of nitrogen-containing products instaed of the expected functional derivatives of 1-alkyl-3-aryltriazene 1-oxides.The structure of these products is a function of the number and chemical nature of the substituents in the diazo component. Keywords: aryldiazonium, triazene, triazene oxide, acetone oxime.
