(E)-4-Meth­oxy-N′-(2,4,5-tri­meth­oxy­benzyl­idene)benzohydrazide hemihydrate

The title compound crystallizes as a hemihydrate, C(18)H(20)N(2)O(5)·0.5H(2)O. The mol­ecule exists in an E conformation with respect to the C=N imine bond. The 4-meth­oxy­phenyl unit is disordered over two sets of sites with a refined occupancy ratio of 0.54 (2):0.46 (2). The dihedral angles betwee...

description The title compound crystallizes as a hemihydrate, C(18)H(20)N(2)O(5)·0.5H(2)O. The mol­ecule exists in an E conformation with respect to the C=N imine bond. The 4-meth­oxy­phenyl 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-meth­oxy-substituted ring. All meth­oxy substituents lie close to the plane of the attached benzene rings [the C(meth­yl)—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 inter­actions.
