SOME twenty compounds, described as 3-keto-l,2-endo-arylimino-l,2-dihydro-l,2-benzisodiazole 1-oxides (I), have been prepared by Chattaway et al.1–8; eleven of these have been reduced by stannous chloride in hydrochloricacid (or, in some cases, by prolonged boiling in ethanol) to deoxy compounds, formulated as (II)2–6.

Nitro functionalized dibromodiazadiene dyes were prepared and fully characterized including X-ray single crystal analysis. Electron deficient dibromodiazadienes were found to be able to act as donors of halogen bonding (XB), while the nitrogroup acted as an acceptor of the XB. Depending on the substituents, the Br···O XB competed with other weak interactions, and for some of the dyes, they even outcompeted
