Abstract: The Schiff base compound, C24H24N2O4, was synthesized by the interaction of 2-hydroxy-3-methoxy benzaldehyde and 1,4-benzene dimethanamine in ethanol, and crystallizes in the monoclinic space group P21/n with Z′ = 0.5. The molecule is not planar, the 1,4-diethylbenzene and the phenol rings are twisted with respect to each other, making a dihedral angle of 74.27 (5)°. The molecular structure is stabilized by an O—H...N hydrogen bond, forming an S(6) ring motif. In the crystal, molecules are linked by C—H...O hydrogen bonds, resulting in the formation of sheets parallel to the bc plane. A Hirshfeld surface analysis was undertaken to investigate the various intermolecular contacts controlling the supramolecular topology, suggesting the H...O (18%) contacts to be the most significant interactions, whereas the H...H (50.5%) and C...H (24.3%) interactions are less significant.
