The asymmetric unit of the title compound, C 12 H 12 N 2 OS, contains two crystallographically independent molecules. Both molecules are essentially planar and stabilized by intraand intermolecular hydrogen-bonding interactions to form one-dimensional zigzag polymeric chains parallel to the c axis.

In the title compund, C~11~H~12~N~2~S, the whole molecule is essentially planar except for methyl H atoms, with a maximum deviation of 0.160 (2) Å for the aniline N atom. The molecule is stabilized by π–π interactions and intermolecular N—H...N hydrogen bonds, which produce dimers located about the
In the title compound, C 11 H 11 FN 2 S, the dihedral angle between the least-squares planes of the fluoroaniline and 1,3-thiazole fragments is 46.47 (17) . The molecules form dimers by N-HÁ Á ÁN hydrogen bonds. There are no significant interactions in the crystal structure.
The molecules of the title compound, C 11 H 11 NOS 2 , form hydrogen-bonded dimers in the solid state. The amide H atom serves as hydrogen-bond donor and the thiocarbonyl S atom of a neighbouring molecule serves as acceptor. The pmethoxyphenyl substituent is tilted by 7.3 (5) from the thiazole-2(3H)
