چکیده
In the title compound, C(30)H(22)BrNO(2), the cyclo-pentane ring of the dihydro-acenaphthyl-ene group and the pyrrolidine ring are both in envelope conformations with the spiro C atom and N atom, respectively, as the flap atom. The cyclo-pentane ring of the indane group adopts a half-chair conformation. A weak intra-molecular C-H⋯O hydrogen bond forms an S(8) ring motif. The naphthalene ring system of the dihydro-acenaphthyl-ene group forms dihedral angles of 41.76 (6) and 42.17 (6)° with the benzene ring of the bromo-phenyl group and the benzene ring of the indane group, respectively. The dihedral angle between the two benzene rings is 83.92 (7)°. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯N hydrogen bonds into a two-dimensional network parallel to the ac plane. Weak C-H⋯π inter-actions are also observed.
