N′-(2-Chlorobenzylidene)-2-fluorobenzohydrazide

Abstract

The title hydrazone compound, C14H10ClFN2O, adopts an E configuration about the C=N double bond. The dihedral angle between the two substituted benzene rings is 11.6 (2)°. The F atom is disordered over two sites with occupancies of 0.488 (2) and 0.512 (2). In the crystal, mol­ecules are linked through inter­molecular N—H⋯O hydrogen bonds, forming chains along the a axis. C—H⋯F and C—H⋯O inter­actions also occur.

N′-(2-Chlorobenzylidene)-2-methylbenzohydrazide

“…The hydrazone compounds have been received much attention for their excellent biological properties (Ajani et al, 2010;Angelusiu et al, 2010;Zhang et al, 2010;Horiuchi et al, 2009) as well as their crystal structures (Ban, 2010;Hussain et al, 2010;Shalash et al, 2010;Khaledi et al, 2009). Recently, the author has reported a hydrazone compound derived from the reaction of 2-chlorobenzaldehyde with 2-fluorobenzohydrazide (Zhang, 2011). In the present paper, the title new hydrazone compound, derived from the reaction of 2-chlorobenzaldehyde with 2-methylbenzohydrazide, is reported.…”
