β¦ Synopsis
The crystal structures of two cinnamanilide derivatives 2 -methyl cinnamanilide (C 16 H 15 N Ocompound I) and 2-methoxy cinnamanilide (C 16 H 15 N O 2 -compound II) are reported. In both crystal structures, the cinnamamide group is almost planar. The inter-planar angle between the two phenyl rings are 71.6(1) o for compound I and 7.5(1) o for compound II. The N-Hβ¦O and C-Hβ¦O type of hydrogen bond interactions between the amide group and the carbonyl group stabilizes the molecular packing as chains in the crystal lattice.
