3,4-Dimethyl-2-(2-oxo-2-phenyl­eth­yl)-2H,4H-pyrazolo­[4,3-c][1,2]benzothia­zine-5,5-dione

In the title mol­ecule, C(19)H(17)N(3)O(3)S, the heterocyclic thia­zine ring adopts a half-chair conformation with the S and N atoms displaced by 0.530 (5) and 0.229 (6) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The ethanone group lies at an angle of 3....

description In the title mol­ecule, C(19)H(17)N(3)O(3)S, the heterocyclic thia­zine ring adopts a half-chair conformation with the S and N atoms displaced by 0.530 (5) and 0.229 (6) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The ethanone group lies at an angle of 3.8 (3)° with respect to the benzene ring, which lies almost perendicular to the pyrazole ring, with a dihedral between the two planes of 89.22 (11)°. Weak inter­molecular C—H⋯O hydrogen-bonding inter­actions are present.
