N′-(3,4-Dimethoxybenzylidene)benzohydrazide

Abstract

The crystal structure of the title Schiff base compound, C16H16N2O3, is characterized by chains of mol­ecules linked by inter­molecular N—H⋯O hydrogen bonds running along the c axis. Further stabilization is provided by weak C—H⋯O contacts. The dihedral angle between the aromatic rings is 38.31 (7)°.

Crystal structure of N′-(5-bromo-2-methoxybenzylidene)-3- methylbenzohydrazide, C16H15BrN2O2

“…The bond lengths and angles are comparable to those found in the similar Schiff base compounds [9][10][11]. There is an intermolecular hydrogen bond in the crystal structure between N2-H2 and O2 atom with d(N2-H2···O2) =2 .815(3) Å, ∠N2-H2···O2 = 161(3)°,which interconnects the title molecules to achain.…”
