In the title compound, C16H14Cl2N2O4·H2O, the hydrazine and water molecules are both located on twofold axes. The C—N—N—C torsion angle is −72.66 (1)° and the dihedral angle between the two benzene rings is 67.33 (1)°. In the crystal, molecules are linked into a layer structure by a combination of O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds. Adjacent layers are linked into a three-dimensional network by Cl⋯Cl interactions [3.400 (2) Å]. C—H⋯π interactions are also observed.

4-chlorophenoxyacetyl chloride (4.10 g, 20 mmol) was dissolved in toluene (20 ml), together with hydrazine hydrate (85%, 0.59 g, 10 mmol). The solution was stirred at room temperature and then pyridine (1.60 g, 20 mmol) was added dropwise. Then the solution was heated at 373 K for two hours. The product was isolated and recrystallized as a colorless solid from ethanol (yield 80.3%).
H atoms on C atoms were positioned geometrically and refined using a riding model with C—H = 0.93Å (aromatic) and 0.97Å (methylene). The Uiso(H) values were set 1.2 times of their parent atoms. H atoms attached to N and O atoms were found from the difference maps and refined with restraints (N—H = 0.86 (1)Å and O—H = 0.82 (1) Å), and their thermal factors were set 1.2 times (for N) or 1.5 times (for O) of the parent atoms.

here.In the title compound (Fig. 1), the hydrazine and water molecules are both located on twofold axes. The torsion angle C8—N1—N1(-x + 5/2, y, -z + 1/2)—C8(-x + 5/2, y, -z + 1/2) is -72.66 (1)° and the dihedral angle between the two benzene rings is 67.33 (1)°. Intermolecular N—H···O and intramolecular O—H···O, C—H···O hydrogen bonds are found in the π interaction [C7···Cg1(x + 1, y, z) = 3.592 (1) Å, Cg1 is the centroid defined by benzene atoms C1—C6] is also observed.

These adjacent layers are linked into a three-dimensional network by the Cl1···Cl1(-x, -y, 1 - z) interaction (3.400 (2) Å, Fig. 3).

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. |

Most diacylhydrazine derivatives have insecticide activity (Zhang et al., 2005; Jia, 2008; Zhao et al., 2008). While in our research of herbicidal compounds, we found some diacylhydrazine derivatives showing herbicidal activity. We have synthesized the title compound and report its crystal structure here.
In the title compound (Fig. 1), the hydrazine and water molecules are both located on twofold axes. The torsion angle C8—N1—N1(-x + 5/2, y, -z + 1/2)—C8(-x + 5/2, y, -z + 1/2) is -72.66 (1)° and the dihedral angle between the two benzene rings is 67.33 (1)°. Intermolecular N—H···O and intramolecular O—H···O, C—H···O hydrogen bonds are found in the crystal structure (Table 1), and one C—H···π interaction [C7···Cg1(x + 1, y, z) = 3.592 (1) Å, Cg1 is the centroid defined by benzene atoms C1—C6] is also observed.
In the crystal packing, the molecules are linked into a two-dimensional layer structure by a combination of O—H···O, N—H···O and C—H···O hydrogen bonds (Fig. 2). These adjacent layers are linked into a three-dimensional network by the Cl1···Cl1(-x, -y, 1 - z) interaction (3.400 (2) Å, Fig. 3).
