CRYSTAL-STRUCTURE OF N-FURFURYL-2-CYANO-3,3-BIS(METHYLENTHIO)ACRYLAMIDE

The crystal acid molecular structure of a -furfuryl-2-cyano-3,3-bis(me thylenthio)acrylamide, C11H10N2S2O2 has been determined by X-ray diffr action. Crystals are monoclinic, space group P2(1/c); a = 8.069(2)Angs trom, b = 15.135(3)Angstrom, c = 9.770(2)Angstrom, = 92.43(3)degrees; Z = 4. The title compound, a furanic derivative obtained from sugar ca ne by-products, has a furanic ring and a five-membered cycle where the re are two S atoms bonded to C atoms. A nominal sing le C (sp(2))-N(sp (3)), C(6)-N(1) bond length is found to be very short at 1.339(5)Angst rom. The molecules in the crystal are held together by an intermolecul ar hydrogen bond N-H...O and by van der Waals forces. There is a weak intramolecular C-H...O interaction.
