N′-[1-(2-Aminophenyl)ethylidene]benzohydrazide

Abstract

The title compound, C15H15N3O, was obtained by a condensation reaction between o-amino­acetophenone and benzoyl hydrazine. The mol­ecule displays an E configuration about the C=N bond. Intra­molecular N—H⋯N hydrogen bonds are formed between the 2-amino­phenyl and imine groups. In the crystal, dimers are formed between mol­ecules linked by inter­molecular N—H⋯O hydrogen bonds from the 2-amino­phenyl group. In addition there are inter­molecular N—H⋯O hydrogen bonds between the amine and carbonyl groups of adjacent mol­ecules. The mol­ecule is twisted rather than planar due to a steric inter­action between the central amide group and the two outer benzene rings. The dihedral angles between this central group and the two rings are 23.29 (9) and 24.96 (9)°.

“…Hydrazones typically act as bi-and tridentate, mono or biprotic depending on the reaction conditions, see: Gup & Kirkan (2005); Naskar et al (2004); Sreeja et al (2003). For bond lengths and angles in similar structures, see: Li & Ban (2009) ;Mao et al (2011);Singh & Singh (2010).…”

N′-(3-Hydroxybenzylidene)-4-nitrobenzohydrazide

“…In the last few months, a number of hydrazone compounds have been reported for their medical applications (Ajani et al, 2010;Angelusiu et al, 2010;Zhang et al, 2010). Recent structure analyses of some members of this family of compounds have also been reported (Ahmad et al, 2010;Huang & Wu, 2010;Ji & Lu, 2010;Khaledi et al, 2010;Singh & Singh, 2010;Zhou & Yang, 2010). In this paper, we report the structure of the new hydrazone compound, N′-(3-hy-…”
