In the title benzohydrazide hydrate, C14H12N2O3·H2O, the dihedral angle between the aromatic rings is 58.11 (6)° and the C=O and N—H groups adopt an anti orientation. The main twist in the molecule occurs about the C(=O)—Car (ar = aromatic) bond, with an N—C(=O)—Car—Car torsion angle of −43.5 (2)°. In the crystal, the components are linked by N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds. These interactions generate [10-1] chains, with adjacent organic molecules linked by inversion symmetry generating either pairs of N—H⋯O links [R22(16) loops] or pairs of O—H⋯O links [R22(20) loops]. Pairs of water molecules are located in the R22(20) loops and form their own O—H⋯O and O—H⋯N hydrogen bonds to adjacent organic molecules in the chain. Finally, an interchain O—H⋯O hydrogen-bond link from the 4-hydroxy group generates (010) sheets.
Keywords: crystal structure; benzohydrazide; hydrate; hydrogen bonding.

1. Related literature
For a related structure, see: Fun et al. (2011). A survey of the Cambridge Structural Database (Version 5.35 of November 2013; Allen, 2002) revealed no fewer than 581 distinct benzohydrazide fragments with different substituents on the aromatic rings and/or other chemical species in the crystal: all bond lengths for the central fragment of the title compound lie close to the mean values for these structures. The only parameter in the metrical survey that shows significant variation is the dihedral angle between the aromatic rings, with the most common value close to zero, and a roughly linear decrease to 90°.

Equimolar quantities of 4-hydroxybenzohydrazide and 3-hydroxybenzaldehyde were refluxed in ethanol for several hours and then cooled to room temperature. Colourless chips of the title compound were obtained by slow evaporation of the solvent at room temperature after several days.

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. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |
