چکیده
The mol-ecule of the title Schiff base compound, C(28)H(32)N(2)O(2), has a twisted geometry, the dihedral angles between the central benzene ring and the other two benzene rings being 29.12 (14) and 26.01 (14)°. Four intra-molecular C-H⋯O hydrogen bonds and two intra-molecular O-H⋯N hydrogen bonds stabilize the mol-ecular structure. In the crystal packing, mol-ecules are stacked along the a axis and stabilized by π-π inter-actions [centroid-centroid distance = 3.6724 (17) Å]. The crystal studied was found to be a non-merohedral twin, the refined ratio of twin components being 0.374 (5):0.626 (5).

The title compound, C(22)H(20)N(2)O(4)·2CHCl(3), a new Schiff base compound, lies across a crystallographic inversion centre. An intra-molecular O-H⋯N hydrogen bond generates a six-membered ring, producing an S(6) ring motif. Inter-molecular bifurcated C-H⋯O hydrogen bonds involving the two O atoms of the Schiff base ligand and the H atom of the chloro-form solvent of crystallization, generate ...
