Abstract: In the title compound, C15H14N4S, the outer phenyl ring makes an angle of 101.4 (2)° with the plane through the inner benzene ring, and the planes of the thiadiazole ring and the attached benzene ring intersect at an angle of 146.7 (2)°. In addition to weak N-HN hydrogen bonds, creating a two-dimensional network parallel to the bc plane of the crystal structure, there is also one non-standard hydrogen-bond interaction of the type C-HN. Stereochemical comparison with the closely related compound 1-[5-(biphenyl-2-yl)-1,3,4-thiadiazol-2-yl]methanaminium chloride shows that the two compounds utilize the same mechanism for anticonvulsant activity.
