11-[(E)-Benzyl-idene]-14-hy-droxy-8-phenyl-6-thia-3,13-diaza-hepta-cyclo-[13.7.1.1(9,13).0(2,9).0(2,14).0(3,7).0(19,23)]tetra-cosa-1(22),15(23),16,18,20-pentaen-10-one.
In the title compound, C(34)H(28)N(2)O(2)S, the piperidine ring adopts a chair conformation. One of the pyrrolidine rings adopts an envelope conformation with the methyl-ene C atom at the flap whereas the other pyrrolidine ring and the thia-zolidine ring adopt half-chair conformations. The mean plane of the dihydro-acenaphthyl-ene ring system [maximum deviation = 0.067 (1) Å] makes dihedral angles of 28.31 (5) and 31.32 (6)° with the two terminal benzene rings. An intra-molecular O-H⋯N hydrogen bond forms an S(5) ring motif. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯S hydrogen bonds into layers lying parallel to the ac plane.
