N'-[(E)-4-Hydr-oxy-3-methoxy-benzyl-idene]benzohydrazide.

ABSTRACT: In the title compound, C(15)H(14)N(2)O(3), the phenyl ring is disordered over two set of sites with an occupancy ratio of 0.810 (3):0.190 (3); the dihedral angle between the two components is 72.3 (4)°. The benzene and phenyl rings are oriented at dihedral angles of 69.18 (8) and 26.0 (5)° (major and minor orientations, respectively), and an intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are linked by N-H⋯O, O-H⋯O and C-H⋯O inter-actions, generating a three-dimensional network.

(E)-4-Hydr-oxy-N'-(2-hydr-oxy-4-methoxy-benzyl-idene)benzohydrazide monohydrate.

Project description:The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·H(2)O, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is almost planar (r.m.s. deviation for all non-H atoms = 0.040 Å). The amido N atom is the hydrogen-bond donor to the water mol-ecule, which is the hydrogen-bond donor to the hydr-oxy groups of two neighboring mol-ecules. One of the hydroxyl groups acts as an intra-molecular and the other as an inter-molecular hydrogen-bond donor.
