2-Amino-5-phenyl-1,3,4-thia­diazo­le at 110 K

The crystal structure of the title compound, C₈H₇N₃S, 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 significant differences in the unit-cell parameters, while the molecular geometry and hydrogen-bonding network are essentially the same in both structures.
