Özet

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.
