CRYSTAL AND MOLECULAR-STRUCTURE OF N-P-TOLYL O-2-CHLORO-4-P-TOLYLAMINO-6-PYRIMIDINECARBOXYAMIDE

The crystal structure of N-p-tolyl -2-chloro-4-p-tolytamino-6-pyrimidi ne-carboxyamide was determined by X-ray diffraction methods. The cryst als are orthorhombic, space group Pbca with a = 11.484(5), b = 15.315( 5), c = 26.68(1) Angstrom, V = 4692(4) Angstrom(3). In the crystal lat tice tile molecule appears to be nearly flat, slightly bow-like shaped . The amide and amine groups form intramolecular N-H...O and N-H...N h ydrogen bonds. Each molecule is linked to two other molecules by inter molecular hydrogen bonds forming chains along a axis.
