Abstract:
The asymmetric unit of the title compound, C44H44N2O6, contains two independent mol-ecules with similar conformations. The di-hydro-naphthalene ring systems are approximately planar [maximum deviations = 0.036 (2), 0.128 (2), 0.0.24 (2) and 0.075 (2) Å]. The dihedral angle between two di-hydro-naphthalene ring systems is 83.37 (4)° in one mol-ecule and 88.99 (4)° in the other. The carbonyl O atom is linked with the adjacent hy-droxy and imino groups via intra-molecular O-H⋯O and N-H⋯O hydrogen bonds. In the crystal, mol-ecules are linked through O-H⋯O hydrogen bonds into layers parallel to (001), and adjacent layers are further stacked by π-π inter-actions between di-hydro-naphthalene and phenyl rings into a three-dimensional supra-molecular architecture. In the crystal, one of the isopropyl groups is disordered over two positions with an occupancy ratio of 0.684 (8):0.316 (8).

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
