2,7-Dibromo-10′H-spiro[fluorene-9,9′-phenanthren]-10′-one

The title racemic spiro compound, C26H14Br2O, crystallizes with two independent molecules (A and B) in the asymmetric unit. The mean plane of the phenanthrene unit is twisted with respect to the mean plane of the fluorene unit by 82.38 (15) and 80.25 (5)° in molecules A and B, respectively. In the c...
