2-(4-Chlorophenoxy)-N′-[2-(4-chlorophenoxy)acetyl]acetohydrazide monohydrate

Abstract

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.
