2,2′,7,7′-Tetra­bromo-9,9′-spiro­bifluorene toluene hemisolvate

There are two independent mol­ecules and one toluene solvent mol­ecule in the asymmetric unit of the title compound, C(25)H(12)Br(4)·0.5C(7)H(8). 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)-h...

Sumario:There are two independent mol­ecules and one toluene solvent mol­ecule in the asymmetric unit of the title compound, C(25)H(12)Br(4)·0.5C(7)H(8). 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.
