| Summary: | The molecule of the title compound, C18H18Cl2N2O2, lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bond. The imino group is coplanar with the aromatic ring. Within the molecule, the planar units are parallel, but extend in opposite directions from the dimethylene bridge. In the crystal structure, the title compound exhibits a layer packing structure via weak π–π stacking interactions [intermolecular plane-to-plane distances between adjacent aromatic rings are 3.461 (3) Å]. Molecules in each layer are linked by intermolecular C—H...O hydrogen-bonding interactions. |
