%X The molecular structure of the title compound, C17H18N2O2, is symmetrical around the central C atom. The two halves of the molecule are related by a twofold rotation axis. In each half of the molecule, the structure is stabilized by intramolecular C¡ªH...O hydrogen bonds. Furthermore, each amide group is almost coplanar with the adjacent benzene ring [dihedral angle is 9.2 (2)¡ã]. The planes of the amide groups are inclined at an angle of 68.5 (1)¡ã, while the two benzene rings make a dihedral angle of 70.40 (3)¡ã. In the crystal, molecules are linked by intermolecular N¡ªH...O hydrogen bonds into chains running along the c axis. Neighbouring chains are weakly coupled by ¦Ð¨C¦Ð stacking interactions [centroid¨Ccentroid distance = 3.7952 (8)  ].
