22′77′-Tetra­bromo-99′-spiro­bifluorene toluene hemisolvate

摘要

There are two independent mol­ecules and one toluene solvent mol­ecule in the asymmetric unit of the title compound, C25H12Br4·0.5C7H8. The dihedral angles between the fluorene ring systems are 85.30 (6) and 84.95 (6)° in the two mol­ecules. The disortions in angles from the ideal sp ³-hybridization geometry around the tetra­hedral C atoms are due to the strain imposed by the central five-membered ring and steric effects.
