1,1′-[o-Phenyl­enebis(nitrilo­methyl­idyne)]di-2-naphthol ethanol hemisolvate

The asymmetric unit of the title compound, C(28)H(20)N(2)O(2)·0.5C(2)H(5)OH, contains two independent mol­ecules of 1,1′-[o-phenyl­enebis(nitrilo­methyl­idyne)]di-2-naphthol, denoted A and B, and one ethanol solvent mol­ecule. The hydr­oxy groups are involved in intra­molecular O—H⋯N hydrogen bonds...

Sumario:The asymmetric unit of the title compound, C(28)H(20)N(2)O(2)·0.5C(2)H(5)OH, contains two independent mol­ecules of 1,1′-[o-phenyl­enebis(nitrilo­methyl­idyne)]di-2-naphthol, denoted A and B, and one ethanol solvent mol­ecule. The hydr­oxy groups are involved in intra­molecular O—H⋯N hydrogen bonds influencing the mol­ecular conformations, which are slightly different in mol­ecules A and B, where the two bicyclic systems form dihedral angles of 51.93 (9) and 58.52 (9)°, respectively. In the crystal structure, a number of short inter­molecular C⋯C contacts with distances of less than 3.5 Å suggest the existence of π–π inter­actions, which contribute to the stability of the crystal packing.
