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.
