In the title compound, C~23~H~25~NO~10~, the five-membered rings adopt envelope conformations and the dihedral angle between the two benzene rings is 67.1 (7)°. The crystal structure is stabilized by intramolecular N—H...O and intermolecular O—H...O hydrogen-bond interactions.
In the title compound, C 13 H 17 N 5 O 2 , the dihedral angle angle between the pyrazole and pyridazine rings is 14.44 (8) . The molecules are linked into a chain along the b axis by C-HÁ Á ÁO hydrogen bonds.
The structure of the title compound, C 22 H 15 ClN 2 O 4 S, comprises non-planar molecules that form a one-dimensional hydrogen-bonded chain via a single N-HÁ Á ÁO interaction, which runs parallel to the b axis. The dihedral angle between the thiazole and quinone rings is 50.43 ( 7) and the dihedral
