Abstract

In the title compound, C(35)H(28)N(2)O(3), an intra-molecular O-H⋯N hydrogen bonds generates a five-membered ring, producing an S(5) ring motif. The piperidone ring adopts a half-chair conformation and the two pyrrolidine rings adopt an envelope conformation. The dihedral angles formed between adjacent benzene rings are 74.39 (5) and 37.70 (6)°. In the crystal crystal, inter-molecular C-H⋯O hydrogen bonds link mol-ecules into dimers, which are further inter-connected into two-dimensional networks parallel to the ac plane by inter-molecular C-H⋯O hydrogen bonds. The crystal structure is consolidated by weak C-H⋯π inter-actions.
