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 π-π stacking inter-actions [centroid-centroid distance = 3.7952 (8) Å].

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
