Abstract

The title compound was synthesized by standard routes of synthesis and its structure was established by spectral and X-ray diffraction
studies. The compound crystallizes in the triclinic space group P-1 with unit cell parameters a=10.4395(6), b=11.9493(6), c=13.8651(7), =
108.958(5), =103.089(5), = 97.885(4), Z=2. The crystal structure was solved by direct methods using single-crystal X-ray diffraction data
collected at room temperature and refined by full-matrix least squares procedures to a final R-value of 0.0664 for 3330 observed reflections.
In the title molecule, the tetrahydropyridine ring adopts a distorted boat conformation and both 4-nitro-phenyl substituents are in axial
positions. The dihedral angle between the planes of the nitro-substituted rings is 45.5(1)o
. The amino group and carbonyl O atom are
involved in intramolecular hydrogen bonding and this interaction leads to the formation of a virtual-six membered ring. In the crystal, CH…O intermolecular interactions stabilizes the crystal packing.

Key words: Tetrahydropyridine ring; crystal structure; direct methods; intermolecular hydrogen bonding.
