Abstract
The molecule of the title Schiff base compound, C16H14I2N2, lies across a crystallographic inversion centre. An intramolecular C—H⋯I hydrogen bond forms a five-membered ring, producing an S(5) ring motif. The C=N bond is coplanar with the benzene ring and adopts a trans configuration. Within the molecule, the planar units are parallel, but extend in opposite directions from the dimethylene bridge. An interesting feature of the crystal structure is the short I⋯N [3.2096 (15) Å] interaction, which is significantly shorter than the sum of the van der Waals radii of these atoms. In the crystal structure, molecules are linked into one-dimensional extended chains along the c axis and also into one-dimensional extended chains along the b axis through short intermolecular I⋯N interactions, forming two-dimensional networks parallel to the bc plane.
