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

In the title compound, C(27)H(20)BrNO(3), the pyrrolidine ring adopts a half-chair conformation, while the other five-membered rings adopt flattened envelope conformations with the spiro C atoms as the flap atoms. An intra-molecular C-H⋯O hydrogen bond occurs, generating an S(6) ring. In the crystal, mol-ecules are connected via weak C-H⋯O hydrogen bonds, forming chains along the c axis.

In the title compound, C(28)H(20)F(3)NO(3), the pyrrolidine ring adopts a half-chair conformation. The other five-membered rings adopt envelope conformations with the spiro and methylene C atoms as the flap atoms. In the crystal, mol-ecules are connected via weak C-H⋯O hydrogen bonds, forming sheets parallel to the bc plane.

The conformation of the title compound, C(27)H(21)NO(3), is stabilized by a weak intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. The pyrrolidine ring adopts a half-chair conformation. Both of the other five-membered rings are in envelope conformations. No significant inter-molecular hydrogen bonds are observed.

In the title compound, C(27)H(20)BrNO(3), two intra-molecular C-H⋯O hydrogen bonds both form S(6) rings. The pyrrolidine ring adopts a twisted conformation about the C-C bond bearing the indane ring systems. The other two five-membered rings within the indane systems are in shallow envelope conformations, with the spiro C atoms as the flap atoms. The mean plane of the pyrrolidine ring [maximum ...
