Abstract
The title compound, C(10)H(10)N(2)O(2)·H(2)O, is dimerized by inversion-related inter-molecular N-H⋯O hydrogen bonding. There is an intra-molecular N-H⋯O bond, resulting in a six-membered ring. Each dimer inter-acts with other dimers through hydrogen bonding with water mol-ecules. The water mol-ecules are linked to each other in a stair-like chain, thus generating two-dimensional polymeric strips. The dimers are also linked to each other through inter-molecular C-H⋯O hydrogen bonding. There are π-π inter-actions between the aromatic and heterocyclic five-membered rings [centroid-centroid distance 3.8360 (12) Å]. C-H⋯π inter-actions also exist between CH(2) groups and aromatic rings.Entities:

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