摘要

The present communication deals with the eco-friendly synthesis, spectral properties and X-ray crystal structure of an alpha-amino acid, 2-(4-chlorophenyl)-2-(4-fluorophenylamino)acetonitrile (1). The title compound (m.f. C14H10CIFN2) crystallizes in the orthorhombic space group Pbcn with the unit-cell parameters : a = 13.9791(4), b = 6.9972(2), c = 25.0724(6) angstrom and Z = 8. 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 0.0494 for 1992 observed reflections. The molecule is organized in the crystal. lattice forming interpenetrating layers. Weak intermolecular van der Waals interactions are responsible for the stability of molecules in the unit cell.
