Almost linear I-Se-Br groups with d(Se-Br)>d(Se-I) occur in 1⋅2 IBr, 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.
在1⋅2 IBr中存在d(Se-Br)>d(Se-I)的近似线性I-Se-Br基团，它是首个与IBr形成的“T形”硒加合物，通过在乙腈中将IBr氧化加成到1,2-双(3-甲基咪唑啉-2-硒基)乙烷(1)上合成得到。密度泛函理论计算表明分子内Br⋅⋅⋅H相互作用是I-Se-Br基团独特结构特征的原因。
