N-(4-fluorophenyl)-2-{[(1E)-(4-methoxyphenyl) methylene]amino}-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide

In the molecule 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 thiophene ( B), fluorophenyl ( C) and methoxyphenyl (D) rings are B/C = 13.65(3)degrees, B/D = 9.72 (2)degrees and C/D = 23.34 (3)degrees. In the crystal structure, intermolecular C-H center dot center dot center dot O hydrogen bonds link the molecules into centrosymmetric dimers; these may be effective in the stabilization of the structure.
