Abstract: Three derivatives of 9,9\'-biacridine, 2,2\'-dihydroxy, 2,2\'-dimethoxy and 2,2\'-diacetoxy have been prepared. The crystal structure of racemic 2,2\'-dimethoxy-9,9\'-biacridine CHCl3 1:1 complex has been determined and shows an almost perpendicular conformation of both acridine rings. 1H NMR experiments using the diacetoxy derivative and both Eu(tfc)3 and R-Pirkle\'s alcohol show the splitting of some signals characteristic of a racemic compound.
Keywords: Biacridines; X-Ray analysis; Lantanide shift reagents; Pirkle\'s alcohol
