- Abstract
A co‐crystalline adduct consisting of a phosphinine selenide and an organohalide was obtained by slow evaporation of the solvent from a mixture of 2,6‐bis(trimethylsilyl)phosphinine selenide and 1,4‐diiodotetrafluorobenzene (1,4‐TFDIB). The crystallographic characterization of the product shows π‐π stacking, F⋅⋅⋅H hydrogen bonding between 1,4‐TFDIB and the phosphinine selenide, as well as F⋅⋅⋅F interactions between 1,4‐TFDIB molecules. Moreover, the phosphorus heterocycle could be crystallized with diiodine to form a 1 : 1 adduct. The d(I−I) distance in this compound is 2.8475(3) Å, which is shorter than the corresponding one in triphenylphosphine selenide diiodide, reflecting the weaker net‐donor power of the phosphinine selenide towards diiodine. The phosphinine selenide could also be used as a selenium transfer reagent to generate KSeCN from KCN.
