Synthesis and crystal structure of 1-(4-{[(e)-4-methoxy-2- hydroxybenzylidene]amino}phenyl)ethanoe oxime

Abstract

The compound 1-(4-{[(E)-4-methoxy-2-hydroxybenzylidene]amino}phenyl)ethanoe oxime with the molecular formula C16H16N2O3, has been synthesized and characterized structurally. The two benzene rings in the molecule form a dihedral angle of 3.05(2). There is one strong intramolecular O-HN hydrogen bond between the hydroxyl (O2-H2) groups and the Schiff base nitrogen (N2) atom, with the distance of d(N2-O2) = 2.593(4) Å. In the crystal structure, each molecule links other three molecules into an infinite 2D supramolecular structure by three pairs of intermolecular O1-H1N1, C1-H1AO1 and C16-H16BO3 hydrogen bonds.
