| Abstract | The title Schiff base compound, C21H26N2O4, exhibits two crystallographically independent molecules in the asymmetric unit with similar conformations. The imino groups are coplanar with the benzene rings; the maximum deviations of the N atoms from the planes comprising the benzene rings and the imino groups are −0.037 (4), 0.013 (4), −0.021 (5), and 0.008 (5) Å. The dihedral angles between the benzene rings in the two molecules are 53.64 (17) and 51.93 (17)°. Strong intramolecular O—H⋯N hydrogen bonds generate S(6) ring motifs. The N atoms are also in close proximity to the H atoms of the dimethylpropane groups, with H⋯N distances between 2.54 and 2.75 Å. The crystal structure is further stabilized by weak intermolecular C—H⋯O hydrogen bonds, weak intermolecular C—H⋯π interactions and π–π contacts involving the imine C atom and two C atoms from the adjacent benzene rings. |
