11-[(E)-Benzyl­idene]-14-hy­droxy-8-phenyl-3,13-diaza­hepta­cyclo­[13.7.1.1(9,13).0(2,9).0(2,14).0(3,7).0(19,23)]tetra­cosa-1(22),15,17,19(23),20-pentaen-10-one

In the title compound, C(35)H(30)N(2)O(2), the piperidine ring adopts a chair conformation and the pyrrolidine ring adopts an envelope conformation. The naphthalene ring makes dihedral angles of 24.56 (3) and 36.13 (4)° with the terminal phenyl rings. The dihedral angle between the two terminal phenyl rings is 55.27 (5)°. One of the C atoms in the pyrrolidine ring is disordered over two sites, with a refined occupany ratio of 0.670 (3):0.330 (3). An intra­molecular O—H⋯N hydrogen bond generates an S(6) ring. In the crystal structure, inversion dimers linked by pairs of C—H⋯O hydrogen bonds generate R (2) (2)(18) loops within sheets of mol­ecules lying parallel to the bc plane.
