Abstract

A Schiff base, (E)-4-Hydroxy-N -(2-methoxybenzylidene) benzohydrazide, (E4HB) had been synthesized in good yield by the acid-catalyzed condensation reaction of 2-methoxybenzaldehyde and 4-hydroxybenzhydrazide in methanolic solution. The synthesized compound was elucidated by elemental analysis (CHN), FTIR, 1H-NMR, 13C-NMR and single crystal X-ray diffraction. E4HB crystallized in the orthorhombic crystal system with space group Z = 8, V = 2656.74(10) Å3 and unit cell parameters a = 14.3951(3) Å, b = 8.7449(2) Å, c =21.1047(4) Å . The crystal structure of the compound is stabilized by intermolecular N1—H1N1….O2, O1—H1O1…O2 and C13—H13A…O1 hydrogen bonds. A π—π interaction with centroid-centroid distance of 3.628 (6) A also occurs (Cg1 = C9— C14, -x, -y, -z).

Keywords: 2-methoxybenzaldehyde; 4-hydroxybenzoylhydrazine; Methanol; Hydrochloric acid
