RESUMO
The title compound, C22H20N4O3S, features two fused six-membered rings linked to a 1,2,3-triazole ring which is attached to an ethyl acetate group. The heterocycle in the benzo-thia-zine residue has an envelope conformation with the S atom being the flap. The conformation of the ethyl acetate side chain, which is directed to the same side of the mol-ecule as the C6 ring of the fused-ring system, may be partially established by a pair of weak intra-molecular C-Hâ¯O(carbon-yl) inter-actions. The three-dimensional packing is aided by inter-molecular C-Hâ¯O and C-Hâ¯N inter-actions.
RESUMO
In the title compound, C15H13NOS, the thia-zine ring adopts a twisted boat conformation and the dihedral angle between the aromatic rings is 86.54â (4)°. In the crystal, mol-ecules are linked by weak C-Hâ¯O inter-actions, resulting in chains along [010].
