title: Crystal structure of 2-ethyl-quinazoline-4(3H)-thione.
abstract: In the title compound, C10H10N2S, all non-H atoms are almost coplanar [maximum deviation = 0.103 (1) Å]. In the crystal, N-H⋯S inter-actions form R 2 (2)(8) rings linking pairs of mol-ecules related by inversion. The mol-ecular pairs are stacked along [100]. A herringbone arrangement of pairs in the [010] direction forms layers parallel to (010).
