2,2'-Diiodoazobenzene

P. J. W. Elder and I. Vargas-Baca

Abstract: The molecular structure of the title compound, C₁₂H₈I₂N₂ [systematic name: (E)-bis(2-iodophenyl)diazene], exhibits an essentially planar trans geometry [maximum deviation = 0.022 (4) Å] with the iodine atoms ortho to the azo bridge. In the crystal, offset [pi] -stacking leads to the formation of columns along the a axis [closest CC distance = 3.383 (4) Å].
