4-Chloro-N′-[(Z)-4-nitrobenzylidene]benzohydrazide monohydrate

Abstract

In the title compound, C 14 H 10 ClN 3 O 3 ·H 2 O, the benzohydrazide group is not planar and the mol­ecule exists in a cis configuration with respect to the methyl­idene unit. The dihedral angle between the two substituted benzene rings is 38.7 (3)°. In the crystal structure, mol­ecules are linked by O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds into a two-dimensional network parallel to the (100) plane. The crystal structure is further stabilized by weak C—H⋯O inter­actions.

N′-(5-Bromo-2-hydroxy-3-methoxybenzylidene)isonicotinohydrazide

“…Hydrazones derived from the reactions of aldehydes with hydrazides show potential biological properties (El-Tabl et al, 2008;Chen et al, 2008;Alvarez et al, 2008;Ventura & Martins, 2008;Kalinowski et al, 2008). In the last few years, a large number of hydrazones have been reported (Peng & Hou, 2008;Shan et al, 2008;Fun et al, 2008;Yehye et al, 2008;Ejsmont et al, 2008). As a continuation of our work in this area (Peng & Hou, 2008) we report here the crystal structure of the title compound, (I), Fig.…”
