Bis(1,3,4-thiadiazol-2-yl) disulfide

Abstract

The title compound, C4H2N4S4, lies about a twofold rotation axis situated at the mid-point of the central S—S bond. Each of two thiadiazole rings is essentially planar, with an rms deviation for the unique thiadiazole ring plane of 0.0019 (7) Å. C—H...N hydrogen bonds link adjacent molecules, forming zigzag chains along the c axis. In addition, these chains are connected by intermolecular S...S interactions [S...S = 3.5153 (11) Å] , forming corrugated sheets, and further fabricate a three-dimensional supramolecular structure by intermolecular N...S contacts [S...N = 3.1941 (17) Å].
