Abstract

In the title compound, C25H21NO7S, the heterocyclic thia­zine ring adopts a half-chair conformation, with the S and N atoms displaced by −0.284 (3) and 0.411 (3) Å, respectively, from the plane formed by the remaining ring atoms; the puckering parameters are: Q = 0.4576 (13) Å, θ = 58.6 (2) and ϕ = 34.3 (3)°. The structure is devoid of any classical hydrogen bonds. However, intra­molecular C—H⋯N and O—H⋯O hydrogen bonds result in six-membered rings and inter­molecular C—H⋯O inter­actions stabilize the crystal structure.
