Abstract
The asymmetric unit of the title compound, C(8)H(6)N(4)O(2)·H(2)O, consists of one 4-(1H-tetra-zol-5-yl)benzoic acid mol-ecule and one water mol-ecule. Hydrogen-bonding and π-π stacking (centroid-centroid distance between tetra-zole and benzene rings = 3.78 Å) inter-actions link the mol-ecules into a three-dimensional network.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. |
