3-Bromo-N′-[(E)-4-hydroxybenzylidene]benzohydrazide

Abstract

The title compound, C14H11BrN2O2, was synthesized by the reaction of 4-hydroxy­benzaldehyde with an equimolar quantity of 3-bromo­benzohydrazide in methanol. The dihedral angle between the two benzene rings is 40.1 (2)°. In the crystal structure, mol­ecules are linked through inter­molecular O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds to form a three-dimensional network.

(E)-N′-(2-Chloro-5-nitrobenzylidene)-4-methoxybenzohydrazide

“…(Zhong et al, 2007;Raj et al, 2007;Jimenez-Pulido et al, 2008). Due to the easy synthesis of such compounds, a great deal of hydrazones have been synthesized and structurally characterized (Yehye et al, 2008;Fun, Patil, Jebas et al, 2008;Yang et al, 2008;Ejsmont et al, 2008). We report herein the crytal structure of the title new hydrazone compound.…”

“…Hydrazone compounds derived from the condensation of aldehydes with hydrazides have been demonstrated to possess excellent biological activities (Zhong et al, 2007;Raj et al, 2007;Jimenez-Pulido et al, 2008). Due to the easy synthesis of such compounds, a number of hydrazone compounds have been synthesized and structurally characterized (Yehye et al, 2008;Fun et al, 2008a,b;Yang et al, 2008;Ejsmont et al, 2008;Yang, 2006). Recently, we have reported a few such compounds (Ban, 2010;Ban & Li, 2008a,b;Li & Ban, 2009a,b).…”
