In the title compound, the molecular packing is mainly driven by N-H···N and N-H···O hydrogen bonding, resulting in the formation of a layered structure.
In the title compound, C6H8N2OS, all atoms except for the methyl H atoms are coplanar, with a maximum deviation of 0.026 (4) angstrom. In the crystal, pairs of molecules are linked by N-H center dot center dot center dot N hydrogen bonds, forming R-2(2)(8) ring motifs. Dimers are connected by N-H center dot center dot center dot O hydrogen bonds, forming layers parallel to the (102) plane. Consolidating the molecular packing, these layers are connected by C-H center dot center dot center dot pi interactions between the center of the 1,3-thiazole ring and the H atom of the methyl group attached to it, as well as C=O center dot center dot center dot pi interactions between the center of the 1,3-thiazole ring and the O atom of the carboxyl group. According to a Hirshfeld surface study, H...H (37.6%), O center dot center dot center dot H/H center dot center dot center dot O (16.8%), S center dot center dot center dot H/H center dot center dot center dot S (15.4%), N center dot center dot center dot H/H center dot center dot center dot N (13.0%) and C center dot center dot center dot H/H center dot center dot center dot C (7.6%) interactions are the most significant contributors to the crystal packing.
