In the title compound, C
17H
17N
3O
3·H
2O, the dihedral angle between the 4,6-dimethyl-pyrazolo[3,4-
b]pyridine-3-one unit [maximum deviation = 0.048 (2) Å] and the phenyl ring is 5.1 (1)°. The structure is characterized by disorder of the carboxylate O atoms, which are split into two parts with a major component of 0.898 (4). In the crystal, the organic molecules and lattice water molecules are linked
via O—H

O, O—H

N and N—H

O hydrogen bonds. The molecules are also linked by C—H

π and weak offset π–π stacking interactions, forming sheets parallel to (001).

Special details top
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell esds are taken
into account individually in the estimation of esds in distances, angles
and torsion angles; correlations between esds in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell esds is used for estimating esds involving l.s. planes. |
