چکیده
The title compound, C(4)H(2)N(4)S(4), lies about a twofold rotation axis situated at the mid-point of the central S-S bond. Each of two thia-diazole rings is essentially planar, with an rms deviation for the unique thia-diazole ring plane of 0.0019 (7) Å. C-H⋯N hydrogen bonds link adjacent mol-ecules, forming zigzag chains along the c axis. In addition, these chains are connected by inter-molecular S⋯S inter-actions [S⋯S = 3.5153 (11) Å] , forming corrugated sheets, and further fabricate a three-dimensional supra-molecular structure by inter-molecular N⋯S contacts [S⋯N = 3.1941 (17) Å].
