✦ Synopsis
The crystal structure of the title compound, C 8 H 7 N 3 S, previously determined at room temperature [Ishankhodzhaeva, Kadyrova, Surazhskaya, Parpiev & Koz'min (2001). Zh. Org. Khim, 37, 759±761], has been redetermined at 110 K. Comparison of the two structures reveals signi®cant differences in the unit-cell parameters, while the molecular geometry and hydrogen-bonding network are essentially the same in both structures.

The title compound, C 9 H 7 N 3 OS 2 , is essentially planar and features an intramolecular OÐHÁ Á ÁN interaction. Centrosymmetrically related molecules associate via NÐHÁ Á ÁS contacts.
In the structure of the the title compound, C 10 H 8 N 6 O, the triazole and oxadiazole rings are almost coplanar. The oxadiazole ring participates in intermolecular N-HÁ Á ÁN hydrogen bonds, forming an infinite network in the ac plane. stacking between parallel oxadiazole rings contributes to the
