1-(2 H -1,3-Benzodioxol-5-yl)ethanone thiosemicarbazone

Abstract

In the title compound, C10H11N3O2S, the 1,3-benzodioxole and hydrazinecarbothioamide fragments are nearly planar [(mean deviations from planarity for non-H atoms of 0.0325 (12) Å and 0.0707 (10) Å, respectively] and subtend a dihedral angle of 29.06 (5)°. In the crystal, molecules are linked by pairs of almost linear N-H...S hydrogen bonds, forming inversion dimers. These dimers are additionally connected by weaker and strongly bent N-H...S interactions into chains along [101]. There is one additional weak N-H...O contact which, if considered as an interaction, leads to the formation of a three-dimensional network.
