Description:
In the title compound, C11H13N3O2S, there is a short intramolecular N—H...N contact. The benzo[d][1,3]dioxole ring system is approximately planar (r.m.s. deviation = 0.025 Å) and makes a dihedral angle of 56.83 (6)° with the mean plane of the methylthiosemicarbazone fragment [–N—N—C(=S)—N—C; maximum deviation = 0.1111 (14) Å for the imino N atom]. In the crystal, molecules are linked via pairs of N—H...S hydrogen bonds, forming inversion dimers. The dimers are connected by N—H...S hydrogen bonds into layers parallel to (100). The H atoms of both methyl groups are disordered over two sets of sites and were refined with occupancy ratios of 0.5:0.5 and 0.75:0.25.
