A new polymorph of 2,5-bis(4-pyridyl)-1,3,4-thiadiazole, C 12 H 8 N 4 S, obtained under hydrothermal conditions, is described. In this structure, the two terminal pyridyl groups are inclined to the central thiadiazole ring with dihedral angles of 6.47 (2) and 29.95 (5) , and the dihedral angle betwe
