The title compound, 2,2'-[(RS,SR)-3,4-diphenyl-2,5-diazahexamethylene]diphenol, which is a tetradentate Schiff base ligand, was prepared and the structure determined in order to investigate the conformation in a metal-free condition. In the crystals, the molecule has a center of symmetry and there is an intramolecular O-HN
hydrogen bond within each salicylideneimine unit.
