چکیده
The complete molecule of the title compound, C(31)H(42)N(2)O(6), is generated by crystallographic twofold symmetry, with one C atom lying on the axis. The dihedral angle between the aromatic rings is 57.03 (6)°. The central heterocyclic ring adopts a half-chair conformation. The mol-ecular conformation is stabilized by two intra-molecular O-H⋯N hydrogen bonds with the N atoms of the heterocyclic ring as the acceptors. In the crystal, mol-ecules are linked into chains along the c axis by non-classical C-H⋯O hydrogen bonds.
