Abstract

In the title compound, C(30)H(26)N(2)O(3), the two pyrrolidine rings adopt twisted and envelope conformations, whereas the cyclo-pentane ring adopts an envelope conformation. The least-squares planes through the pyrrolidine rings form a dihedral angle of 41.72 (10)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯N hydrogen bond, which generates an S(5) ring motif. Centrosymmetrically related mol-ecules are linked via two pairs of inter-molecular C-H⋯O inter-actions, forming R(2) (2)(16) ring motifs. In the crystal packing, the mol-ecules are linked into two-dimensional networks parallel to the ab plane via C-H⋯O inter-actions.
