Abstract
In the title compound, C10H10N2S, all non-H atoms are almost coplanar [maximum deviation = 0.103 (1) angstrom]. In the crystal, N-H center dot center dot center dot S interactions form R-2(2) (8) rings linking pairs of molecules related by inversion. The molecular pairs are stacked along [100]. A herringbone arrangement of pairs in the [010] direction forms layers parallel to (010).
