(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.

N'-(4-Hydr-oxy-3-methoxy-benzyl-idene)acetohydrazide monohydrate.

Project description:In the title compound, C(10)H(12)N(2)O(3)·H(2)O, the Schiff base mol-ecule is approximately planar [within 0.189?(1)?Å].

The hydr-oxy H atom deviates from the 4-hydr-oxy-3-methoxy-phenyl mean plane by 0.319?(2)?Å, probably due to the involvement of this H atom in the O-H?O hydrogen bond. The weak O-H?O hydrogen bond is involved in a bifurcated hydrogen bond with R(1) (2)(4) motif. A weak C-H?? inter-action is also present.
