4'-(4-Chlorophenyl)-1'-methyldispiro[indan-2,2'-pyrrolidine-3',2''-indan]-1,3,1''-trione.

ABSTRACT: In the title compound, C(27)H(20)ClNO(3), the two cyclo-pentane rings adopt envelope conformations. The pyrrolidine ring also adopts an envelope conformation (with the spiro C atom as the flap) and its least-squares plane (fitted to five atoms) makes dihedral angles of 66.50 (9), 77.36 (8) and 73.76 (8)° with the chloro-benzene ring and the two 2,3-dihydro-1H-indene ring systems, respectively. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds into chains running parallel to the [001] direction.
