چکیده
The title Schiff base compound, C(16)H(14)ClN, adopts E configurations with respect to both the C=C and C=N bonds. The dihedral angle between the two aromatic rings is 53.27 (4)°, while the plane through the C=C-C=N system is inclined at 9.06 (8)° to the benzene ring and 44.92 (5)° to the chloro-benzene ring. In the crystal structure, weak C-H⋯Cl and C-H⋯N hydrogen bonds stack the mol-ecules down the a axis.
