The asymmetric unit of the title Schiff base compound, C(21)H(26)N(2)O(4), consists of four crystallographically independent mol­ecules, viz. A, B, C and D. The A and D, and the B and C mol­ecules are related by a pseudo-inversion centre, and the remaining pairs of mol­ecules differ in the orientati...

description The asymmetric unit of the title Schiff base compound, C(21)H(26)N(2)O(4), consists of four crystallographically independent mol­ecules, viz. A, B, C and D. The A and D, and the B and C mol­ecules are related by a pseudo-inversion centre, and the remaining pairs of mol­ecules differ in the orientations of one of the meth­oxy groups. In each independent mol­ecule, intra­molecular O—H⋯N hydrogen bonds generate two S(6) ring motifs. The dihedral angles between the benzene rings in mol­ecules A, B, C and D are 65.86 (19), 50.41 (19), 68.59 (19) and 50.85 (19)°, respectively. In the crystal structure, mol­ecules are linked by C—H⋯O hydrogen bonds, forming R (2) (2)(8) dimers. In addition, weak C—H⋯π inter­actions are observed.
