9-(p-Methylpheny)-9-fluorenol

P. D. Robinson, A. W. McLean and C. Y. Meyers

Abstract: The title compound, C₂₀H₁₆O, has two molecules in the asymmetric unit, of nearly identical conformations, linked via O-HO-H, as well as O-H(fluorene) intermolecular hydrogen bonds. The 9-aryl and fluorene rings of both molecules deviate substantially from perpendicularity. Although the crystals melt sharply without molecular decomposition, the melt fails to recrystallize when cooled, even after a long period. Similar phenomena are observed with other crystalline 9-alkylphenyl-9-fluorenols that exhibit intermolecular (arene) interactions.
