(E)-2-Cyano-3-[4-(dimethyl-amino)phen-yl]-N-phenyl-prop-2-enamide

Abstract

In the title compound, C18H17N3O, the dihedral angle between the phenyl and benzene rings is 11.22 (14)°. Apart from the methyl H atoms, the mol-ecule is close to planar, with a maximum deviation of 0.145 (3) Å. Intra-molecular C - H⋯O and C - H⋯N inter-actions occur. In the crystal, inversion dimers linked by pairs of N - H⋯N hydrogen bonds occur, resulting in an R 2 2(12) ring motif. Further C - H⋯N and C - H⋯O bonds generate R 1 2(7) and R 2 2(22) motifs and a C - H⋯π inter-action also occurs.
