In the title compound, C 17 H 15 N 3 O 5 SÁC 2 H 6 OS, the thiazine ring adopts a distorted half-chair conformation. The enolic H atom is involved in both intramolecular and intermolecular O-HÁ Á ÁO hydrogen bonds, the latter linking the molecules into centrosymmetric pairs. Both anthranilamide H at

In the crystal structure of the title compound, C~15~H~12~Cl~2~O~2~, the chloro-substituted benzene rings are not parallel; the other rings are nearly parallel and the molecules stack in layers parallel to these rings. There are two molecules in the asymmetric unit.
In the title compound, C 19 H 20 N 2 O 5 Á0.19H 2 O, the coumarin moiety is oriented almost perpendicular to the plane of the pyrazole ring. The crystal structure is stabilized by weak intermolecular CÐHÁ Á Á% interactions.
ÁCl À , contains two crystallographically independent cations and two chloride ions. The crystal structure is stabilized by intramolecular O-HÁ Á ÁO, and intermolecular N-HÁ Á ÁCl and O-HÁ Á ÁCl hydrogen bonds.
The structure of the title compound, C 13 H 10 O 4 , which was synthesized by the reaction of salicylaldehyde and 4-hydroxy-6-methyl-2H-pyran-2-one in the presence of triethylbenzylammonium chloride in aqueous media, was previously determined at room temperature [March, Moreno-Manas, Roca, Germain,
