4'-(4-Bromo-phen-yl)-1'-methyl-dispiro-[indan-2,2'-pyrrolidine-3',2''-indan]-1,3,1''-trione.

ABSTRACT: 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.

Project description:The asymmetric unit of the title compound, C29H24FNO5·0.5CH3OH, contains two independent mol-ecules and a one methanol solvent mol-ecule. The methanol mol-ecule is O-H?O hydrogen bonded to one of the independent mol-ecules.

The fluoro-substituted benzene ring forms dihedral angles of 65.35?(6) and 85.87?(7)° with the indane group benzene rings in one mol-ecule, and 72.78?(8) and 77.27?(8)° in the other. In each mol-ecule, a weak intra-molecular C-H?O hydrogen bond forms an S(6) ring motif. In the crystal, weak C-H?O, C-H?N and C-H?F hydrogen bonds link the mol-ecules into a three-dimensional network.
