Abstract
The crystal structure of substituted purine derivative, 8-(3-butyl-4-phenyl-2,3-dihydrothiazol-2-ylidene)hydrazino-3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-diones, caffeine derivative, has been determined. It crystallized in monoclinic system and space group P21/c with unit cell parameters a = 15.2634 (9), b = 13.4692 (9), c = 11.9761 (7) Å, and β = 108.825 (3)°. Although each constituting moiety of the structure individually is planar, nonplanar configuration for the whole molecule was noticed. Molecular mechanics computations indicated the same nonplanar feature of the whole molecule. A network of intermolecular hydrogen bonds contacts and π interactions stabilized the structure.
