Methyl 4-hy­droxy-2-meth­oxy­carbonyl­methyl-1,1-dioxo-1,2-dihydro-1λ(6),2-benzothia­zine-3-carboxyl­ate

There are two independent mol­ecules in the asymmetric unit of the title compound, C(13)H(13)NO(7)S, which have almost identical geometries. The thia­zine ring adopts a sofa conformation in both mol­ecules and the mol­ecular conformations are stabilized by intramolecular O—H⋯O hydrogen bonds. Inter­...

Sumario:There are two independent mol­ecules in the asymmetric unit of the title compound, C(13)H(13)NO(7)S, which have almost identical geometries. The thia­zine ring adopts a sofa conformation in both mol­ecules and the mol­ecular conformations are stabilized by intramolecular O—H⋯O hydrogen bonds. Inter­molecular C—H⋯O hydrogen bonds stabilize the crystal packing.
