In the title salt dihydrate, the conrotatory relationship between the carboxylate and nitro groups of the anion leads to a dihedral angle between them of 26.73 (15)°. Substantial charge-assisted water-O—H
O(carboxylate) hydrogen bonding leads to supramolecular zigzag chains. These are connected into a three-dimensional architecture by N—H
O and N—H
N hydrogen bonds.

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. |
