Abstract: The title compound, C22H26N2O2, crystallizes with three independent molecules, two of which are situated on inversion centers, so the asymmetric unit contains two independent half-molecules and one molecule in a general position. The two hydroxy groups in each molecule are involved in intramolecular O-HN hydrogen bonds, which generate S(6) rings. In the crystal, weak intermolecular C-H interactions link the molecules into two crystallographically independent columns propagating along ; one column consists of molecules in general positions, while the other column is built from alternating independent centrosymmetric molecules.
