(E)-4-Meth-oxy-N'-(2,4,5-tri-meth-oxy-benzyl-idene)benzohydrazide hemihydrate.

ABSTRACT: The title compound crystallizes as a hemihydrate, C18H20N2O5·0.5H2O. The mol-ecule exists in an E conformation with respect to the C=N imine bond. The 4-meth-oxy-phenyl unit is disordered over two sets of sites with a refined occupancy ratio of 0.54?(2):0.46?(2). The dihedral angles between the benzene rings are 29.20?(9) and 26.59?(9)°, respectively, for the major and minor components of the 4-meth-oxy-substituted ring. All meth-oxy substituents lie close to the plane of the attached benzene rings [the Cmeth-yl-O-C-C torsion angles range from -4.0?(12) to 3.9?(2)°]. In the crystal, the components are linked into chains propagating along [001] via N-H?O and O-H?O hydrogen bonds and weak C-H?O inter-actions.
