2,2′-Diiodoazobenzene
Abstract
The mol-ecular structure of the title compound, C(12)H(8)I(2)N(2) [systematic name: (E)-bis-(2-iodo-phen-yl)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 π-stacking leads to the formation of columns along the a axis [closest C⋯C distance = 3.383 (4) Å].
