Abstract:The title compound has synthesized and its crystal structure was determined by X-ray analysis. The crystal belongs to monoclinic, space group C2/c with a = 10.413(3), b = 16.080(5), c = 19.188(6)A,β = 94.023(7)°, V = 3205(2)A3, Z = 8, Dc =1.440 g/cm3, F(000) = 1424,μ(MoKα) = 0.238 mm-1, S = 0.896, R = 0.0454 and Wr = 0.0998 for 1914 observed reflections with I ≥ 2σ(I). In the title compound (C18H12F3NOS), the side-chain carbonyl group, the adjacent double bond and the amine N from 2-naphthylamine are essentially coplanar with the largest deviation from this plane being -0.018(2) A For atom C(3). The dihedral angle between the mean plane and the thienyl ring is 4.24(3)°. A strong intramolecular N-H…O hydrogen bond (N…O 2.666(3)°and N-H…O 142(3)°) was observed, which leads to an enamine tautomer in the crystal.
