1-(2 H -1,3-Benzodioxol-5-yl)ethanone thiosemicarbazone
(2013) Oliveira, Adriano Bof de; Farias, Renan Lira de; Näther, Christian; Jess, Inke; Bresolin, Leandro
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.

1-(5-Bromo-2-oxoindolin-3-ylidene)thiosemicarbazone
(2013) Bandeira, Katlen Crhistian Tribuzy; Bresolin, Leandro; Näther, Christian; Jess, Inke; Oliveira, Adriano Bof de
The title molecule, C9H7BrN4OS, is essentially planar [r.m.s. deviation = 0.066 (2) Å], the maximum deviation from the mean plane through the non-H atoms being 0.190 (3) Å for the terminal amine N atom. In the crystal, molecules are linked through N-H...O and N-H...S interactions, generating infinite chains along the b-axis direction. In turn, the chains are stacked along the a axis via [pi]-[pi] interactions [centroid-centroid distance = 3.470 (2) Å] and further connected by N-H...Br interactions into a three-dimensional network. An intramolecular N-H...O hydrogen bond is also observed.
