N,N′-Bis(2,6-dichlorobenzylidene)propane-1,2-diamine

In the title Schiff base, C17H14Cl4N2, the atoms of one of the 2,6-dichlorobenzylidene units and the central 1,2-diaminopropane grouping are disordered over two sets of sites in a 0.8838 (12):0.1162 (12) ratio. The dihedral angles between the ordered benzene ring and its disordered counterparts are 57.41 (12) and 54.8 (6)° for the major and minor disorder components, respectively. The crystal studied was a racemic twin, the refined ratio of the twin components being 0.37 (5):0.63 (5).
