Abstract

Almost linear I‐Se‐Br groups with d(Se−Br)>d(Se−I) occur in 1⋅2 IBr (see structure), the first “T‐shaped” Se adduct with IBr, which was synthesized by the oxidative addition of IBr to 1,2‐bis(3‐methylimidazoline‐2‐selonyl)ethane (1) in MeCN. Density functional theory calculations indicate the intramolecular Br⋅⋅⋅H interactions as being responsible for the peculiar structural features of the I‐Se‐Br groups.
