4-Hy-droxy-3-(3-meth-oxybenzoyl)-2-[(3-meth-oxybenzoyl)methyl]-2H-1,2-benzothia-zine 1,1-dioxide.

ABSTRACT: In the title compound, C(25)H(21)NO(7)S, the heterocyclic thia-zine 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, intra-molecular C-H⋯N and O-H⋯O hydrogen bonds result in six-membered rings and inter-molecular C-H⋯O inter-actions stabilize the crystal structure.
