Abstract

Molecules of 2-amino-5-trifluoromethyl-1,3,4-thiadiazole, C3H2F3N3S, are linked by two independent N-H (...) N hydrogen bonds into sheets of alternating R-2(2)(8) and R-6(6)(20) rings, while the molecules of the unsubstituted 2-amino-1,3,4-thiadiazole, C2H3N3S, are linked, again by two independent N-H (...) N hydrogen bonds, but into chains of edge-fused R-2(2)(8) and R-4(4)(10) rings.
