Crystal structure of (E)-2-[1-(benzo[d][1,3]dioxol-5-yl)ethylidene]-N-methylhydrazine-1-carbothioamide

What is it about?

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.
