5-Ethyl-5-methyl-4-phenyl-5H-1,2,4-triazol-3(4H)-thione

Abstract

The five-membered ring of the title compound δ1-1,2,4- triazoline-5-thione, C11H13N3S, is almost planar (r.m.s. deviation = 0.009 Å); the phenyl ring is aligned at 84.6 (2)° with respect to the five-membered ring. The crystal studied was a racemic twin with an approximate 20% minor twin component. Weak intermolecular C-H⋯N hydrogen bonding is present in the crystal structure.
