Crystal structure of (Z)-ethyl 2-{5-[(2-benzyl-idene-3-oxo-2,3-di-hydro-benzo[b][1,4]thia-zin-4-yl)meth-yl]-1H-1,2,3-triazol-1-yl}acetate. 2015

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-H⋯O(carbon-yl) inter-actions. The three-dimensional packing is aided by inter-molecular C-H⋯O and C-H⋯N inter-actions.
