Crystal Structure of 1-N-Methyl[2,2']spiro-acenaphthene-1'-one[3,2"]spiro-cyclohexane-1"-one-4-[p-methylphenyl]pyrrolidine

Abstract

The title compound (C28H27NO2) crystallizes in monoclinic space group P21/c with a molecule in the asymmetric unit. The structure was solved by direct methods and refined by full-matrix least-squares procedures to final R = 0.0788 and wR = 0.2022 using 3083 reflections. The pyrrolidine and cyclohexane rings adopt envelope and chair conformations, respectively. The molecules are stabilized by C-H…O type intra and intermolecular interactions in addition to van der Waals forces.
