Bottom Line: Both mol-ecules are slightly twisted; the central 1,2,4-triazolo[3,4-b]-1,3,4-thia-diazine ring system makes dihedral angles of 9.65 (15) and 13.29 (15)° with the pyridine and benzene rings, respectively, in one mol-ecule, whereas the corresponding values in the other mol-ecule are 9.30 (15) and 4.84 (15)°.A weak intra-molecular C-H⋯N inter-action with an S(6) ring motif is observed in each mol-ecule.In the crystal, the independent mol-ecules are each linked through N-H⋯N hydrogen bonds and weak C-H⋯N interactions into ribbons along the c axis.

ABSTRACT
In the asymmetric unit of the title compound, C(16)H(12)BrN(7)S, there are two crystallographically independent mol-ecules with similar conformations. Both mol-ecules are slightly twisted; the central 1,2,4-triazolo[3,4-b]-1,3,4-thia-diazine ring system makes dihedral angles of 9.65 (15) and 13.29 (15)° with the pyridine and benzene rings, respectively, in one mol-ecule, whereas the corresponding values in the other mol-ecule are 9.30 (15) and 4.84 (15)°. A weak intra-molecular C-H⋯N inter-action with an S(6) ring motif is observed in each mol-ecule. In the crystal, the independent mol-ecules are each linked through N-H⋯N hydrogen bonds and weak C-H⋯N interactions into ribbons along the c axis. The ribbons are further linked together by weak C-H⋯N, C-H⋯π and π-π [centroid-centroid distances = 3.572 (2)-3.884 (2) Å] inter-actions.
