Аннотация

The molecular and crystal structure of perfluoro-9,10-diphenylanthracene and its perfluorinated dihydro derivatives (9,10-diphenyl-1,4-dihydroanthracene, 9,10-diphenyl-2,9-dihydroanthracene, and cis,trans- 9,10-diphenyl-9,10-dihydroanthracenes) is determined by single crystal X-ray diffraction. 9,10-Diphenyl- 2,9-dihydroanthracene is analyzed in cocrystal with 9,10-diphenyl-1,4-dihydroanthracene (2:1). It is shown that in the studied compounds the angles between the planes of the phenyl rings and the anthracene core are close to 90°. According to the DFT/B3LYP/6-31G(d) calculations, 9,10-diphenyl-1,4-dihydroanthracene is most thermodynamically stable among the studied dihydroanthracenes. There are C–F…π interactions and no π-stacking interactions in the crystals of the studied compounds.
