N-(4-Fluoro-phen-yl)-2-(1E)-(4-methoxy-phen-yl)methyl-eneamino-4,5,6, 7-tetra-hydro-1-benzothio-phene-3-carboxamide

In the mol-ecule of the title compound, C24H21FN2O2S, the fused six-membered ring has a half-chair conformation, with a pseudo-twofold axis passing through the mid-points of the bridgehead C - C bond and the opposite C - C bond. The dihedral angles between the planar thio-phene (B), fluoro-phenyl (C) and methoxy-phenyl (D) rings are B/C = 13.65 (3)°, B/D = 9.72 (2)° and C/D = 23.34 (3)°. In the crystal structure, inter-molecular C - Hâ¯O hydrogen bonds link the mol-ecules into centrosymmetric dimers; these may be effective in the stabilization of the structure. © 2007 International Union of Crystallography.
