2-(2,3,5,6-Tetrafluoro-4-iodoanilino)-ethanol

Abstract

The reaction of 2-amino-ethanol and iodo-penta-fluoro-benzene in the presence of K2CO3 gave the title compound, C8H6F4INO, in high yield. The structure is characterized by double layers of mol-ecules linked by O - H⋯O and N - H⋯O hydrogen bonds, and linear C - I⋯F [I⋯F = 3.049 (2) Å] and bent C - I⋯I [I⋯I = 3.9388 (7) Å] inter-actions between pairs of nearly parallel iodo-tetra-fluoro- phenyl groups. No O⋯I or N⋯I halogen bonding is found. © International Union of Crystallography 2008.
