摘要：

The title compound, C27H29F3O5, is a liquid crystal (LC) and exhibits enantiotropic SmA phase transitions. In the crystal, the dihedral angle between the 2H-chromene ring system and the benzene ring is 62.97 (2)degrees. The three F atoms of the -CF3 group are disordered over two sets of sites with occupancy factors 0.71 (4): 0.29 (4). In the crystal, pairs of C-H center dot center dot center dot O hydrogen bonds form inversion dimers and generate R-2(2) (10) rings. The structure also features C-H center dot center dot center dot F and C-H center dot center dot center dot pi interactions along [100] and [010], respectively.
