Abstract
The title compound, C30H18O3, was obtained by light irradiation of a dichloroethane solution of 9-anthroyl chloride and 9-anthroic acid. The molecules, which possess approximately mm2 local symmetry, are packed in columns, the oxygenated moieties facing each other according to the symmetry of a monoclinic lattice. The space group of the crystal is P21/c, with a whole molecule as the asymmetric unit. The structure is compared with those of similar dianthracene derivatives.File in questo prodotto:
