4-Methyl-3-phenyl-2,4-dihydro-pyrazolo-[4,3-c][1,2]benzothia-zine 5,5-dioxide.

ABSTRACT: In the title mol-ecule, C(16)H(13)N(3)O(2)S, the heterocyclic thia-zine ring adopts a twist chair conformation with the S atom and an adjacent C atom displaced by 0.946?(5) and 0.405?(6)?Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The mean planes of the benzene rings make dihedral angles of 16.61?(10) and 15.32?(10)° with the mean plane of the pyrazole ring. The mol-ecular structure is consolidated by intra-molecular C-H?N inter-actions and the crystal packing is stabilized by N-H?O and C-H?N hydrogen bonds. The crystal studied was an inversion twin with the refined ratio of the twin components being 0.53?(11):0.47?(11).

In addition, inter-molecular C-H?O inter-actions result in chains of mol-ecules along the c axis, further consolidating the crystal packing.

Methyl 3-hydr-oxy-4-oxo-3,4-dihydro-2H-1,2-benzothia-zine-3-carboxyl-ate 1,1-dioxide monohydrate.

Project description:In the mol-ecule of the title compound, C(10)H(9)NO(6)S·H(2)O, the benzothia-zine ring adopts an envelope conformation. An intra-molecular N-H?O hydrogen bond results in the formation of a nonplanar five-membered ring which has a twisted conformation. In the crystal structure, inter-molecular N-H?O, O-H?O and C-H?O hydrogen bonds link the mol-ecules to form a three-dimensional network. There is a ?-? contact between the benzene rings [centroid-centroid distance = 3.972?(2)?Å].
