Abstract: The crystal structures of two cocrystals composed of 4,4'-(fluorene-9,9-diyl)diphenol (C₂₅H₁₈O₂) and 6-methyl-2H-pyridone (C₆H₇NO) are reported, namely 4,4'-(fluorene-9,9-diyl)diphenol-6-methyl-2H-pyridone (1/2), C₂₅H₁₈O₂·2C₆H₇NO, (I), and 4,4'-(fluorene-9,9-diyl)diphenol-6-methyl-2H-pyridone-water (1/3/3), C₂₅H₁₈O₂·3C₆H₇NO·3H₂O, (II). In both cocrystals, the mutual orientation between two 6-methyl-2H-pyridone molecules in principle enables photodimerization, yet in both cases no photodimerization occurs. In cocrystal (I) this is probably due to poor orbital overlap, while in the case of cocrystal (II) it is suggested that the lack of reaction is due to the highly complex hydrogen-bonding network that exists in the structure.

Formula: C₂₅H₁₈O₂·2C₆H₇NO and C₂₅H₁₈O₂·3C₆H₇NO·3H₂O
