Crystal Structure of 2-methyl cinnamanilide and 2-methoxy cinnamanilide

The crystal structures of two cinnamanilide derivatives 2-methyl cinnamanilide (C16H15NO – compound I) and 2-methoxy cinnamanilide (C16H15NO2 – 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)° for compound I and 7.5(1)° for compound II. The N-H…O and C-H…O type of hydrogen bond interactions between the amide group and the carbonyl group stabilizes the molecular packing as chains in the crystal lattice.

Keywords: crystal structure, cinnamanilides, ring conformation
