6-(4-Bromophenyl)-3methyl-7H-1,2,4-triazolo[3,4-b][1,3,4]thiadiazine

Abstract

In the title compound, C11H9BrN4S, the 1,2,4-triazole ring is essentially planar (r.m.s. deviation = 0.020 Å) and makes a dihedral angle of 29.1 (5)°with the bromobenzene ring. The 3,6-dihydro-1,3,4-thiadiazine ring adopts a twist-boat conformation. In the crystal, molecules are linked by C - H⋯N interactions into sheets lying parallel to the (010) plane. The same N atom accepts two such hydrogen bonds.
