Key indicators: single-crystal X-ray study; T = 295 K; mean (C-C) = 0.008 Å; R factor = 0.052; wR factor = 0.148; data-to-parameter ratio = 8.8. White single crystals of the title compound, C 36 H 18 N 4 O 2 ÁC 6 H 6 , were obtained by reacting (R)-(+)-1,1 0 -bi-2-naphthol with 3nitrophthalonitrile and potassium carbonate and were recrystallized from benzene. The dihedral angle between the two naphthyl rings is 79.5(5) . The (R)-(+)-2,2'-Bis(2,3-dicyanophenyl)-1,1'-binaphthyl units aredoi:10.1107/s1600536807040639 fatcat:xv63yqzdzvggnftqv3gdzmpz5a
