N,N'-Bis(2-iodo-benzyl-idene)ethane-1,2-diamine.

ABSTRACT: The mol-ecule of the title Schiff base compound, C(16)H(14)I(2)N(2), lies across a crystallographic inversion centre. An intra-molecular 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 mol-ecule, the planar units are parallel, but extend in opposite directions from the dimethyl-ene bridge. An inter-esting feature of the crystal structure is the short I?N [3.2096?(15)?Å] inter-action, which is significantly shorter than the sum of the van der Waals radii of these atoms. In the crystal structure, mol-ecules are linked into one-dimensional extended chains along the c axis and also into one-dimensional extended chains along the b axis through short inter-molecular I?N inter-actions, forming two-dimensional networks parallel to the bc plane.
