4-[(1-Benzyl-1,2,3-triazol-5-yl)meth-yl]-2H-1,4-benzo-thia-zin-3(4H)-one.
The asymmetric unit of the title compound, C18H16N4OS, contains two independent mol-ecules of similar conformation, the most relevant difference being the dihedral angle formed by the benzene rings [57.8 (2) and 52.7 (2)°]. The six-membered heterocycle of the benzo-thia-zine fragment exhibits a screw-boat conformation in both mol-ecules. The plane through the triazole ring is nearly perpendicular to those through the fused and terminal benzene rings [dihedral angles of 74.2 (2) and 83.2 (2)° in one mol-ecule, and 77.8 (2) and 82.9 (2)° in the other]. In the crystal, mol-ecules are linked by C-H⋯N and C-H⋯O hydrogen bonds into chains parallel to the a-axis direction. The crystal used was a non-merohedral twin, the refined ratio of twin components being 0.85 (10):15 (10).
