Abstract: In the title compound, C₂₆H₃₆N₄O₄, the two phenyl rings are almost parallel, making a dihedral angle of 2.54 (6)°. The piperazine ring adopts a chair conformation, with the substituents on the N atoms both lying in equatorial positions so that the molecule has an extended conformation and is pseudocentrosymmetric. The crystal structure is stabilized by intramolecular and intermolecular O-HN hydrogen bonds and weak C-HO interactions.
