N,N'-Bis(3-methyl-phen-yl)propane-diamide.

ABSTRACT: The mol-ecular structure of the title compound, C(17)H(18)N(2)O(2), is symmetrical around the central C atom. The two halves of the mol-ecule are related by a twofold rotation axis. In each half of the mol-ecule, the structure is stabilized by intra-molecular C-H?O hydrogen bonds. Furthermore, each amide group is almost coplanar with the adjacent benzene ring [dihedral angle is 9.2?(2)°]. The planes of the amide groups are inclined at an angle of 68.5?(1)°, while the two benzene rings make a dihedral angle of 70.40?(3)°. In the crystal, mol-ecules are linked by inter-molecular N-H?O hydrogen bonds into chains running along the c axis. Neighbouring chains are weakly coupled by ?-? stacking inter-actions [centroid-centroid distance = 3.7952?(8)?Å].
