✦ 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.
