Abstract

The asymmetric unit of the title compound, 2C15H15N3O3S·H2O, comprises two crystallographically independent organic molecules and one water molecule, all in general positions. Each organic molecule comprises an indazolyl system linked through a sulfonamide group to a methoxybenzene ring. The most important difference between the two organic molecules is the dihedral angle between the fused-ring system and the methoxybenzene ring, which is 56.32 (7)° in one molecule and 35.35 (8)° in the other. In the crystal, the organic and water molecules are connected into supramolecular chains along thecaxis through O—H...N, O—H...O, N—H...O and N—-H...N hydrogen bonds; in addition, a π–π interaction between pyrazolyl rings [inter-centroid separation = 3.7547 (12) Å] is noted.
