Crystal structure of 2-amino-N-(2-fluoro-phen-yl)-4,5,6,7-tetra-hydro-1-benzo-thio-phene-3-carboxamide.

In the title compound, C15H15FN2OS, the dihedral angle between the planes of the benzo-thio-phene ring system and the fluoro-benzene ring is 3.74 (14)°. The six-membered ring of the benzo-thio-phene moiety adopts a half-chair conformation. The mol-ecular conformation is consolidated by intra-molecular N-H⋯F and N-H⋯O hydrogen bonds. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating C(6) [001] chains.

2-Amino-N-(2-methoxy-phen-yl)-4,5-dimethyl-thio-phene-3-carboxamide.

In the title compound, C(14)H(16)N(2)O(2)S, the two aromatic rings make a dihedral angle of 13.9 (1)°. The crystal structure is stabilized by both inter- and intra-molecular N-H⋯O, C-H⋯O and C-H⋯N hydrogen bonds.
