16-[(E)-Benzylidene]-13-hydroxy-4-methyl-2-phenyl-4,14-diazapentacyclo-[12. 3.1.01,5.05,13.07,12]octadeca-7(12),8,10- triene-6,17-dione

Abstract

In the title compound, C30H26N2O 3, the two pyrrolidine rings adopt twisted and envelope conformations, whereas the cyclopentane ring adopts an envelope conformation. The least-squares planes through the pyrrolidine rings form a dihedral angle of 41.72 (10)°. The molecular structure is stabilized by an intra-molecular O-H⋯N hydrogen bond, which generates an S(5) ring motif. Centrosymmetrically related molecules are linked via two pairs of inter-molecular C-H⋯O inter-actions, forming R22(16) ring motifs. In the crystal packing, the molecules are linked into two-dimensional networks parallel to the ab plane via C-H⋯O inter-actions.
