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 -stacking leads to the formation of columns along the a axis [closest CC distance = 3.383 (4) Å].
