2,2-Difluoro-4-phenyl-1,3,2-dioxaborolo[4,5-c]chromen-5-ium-2-ide

Abstract

In the crystal, the inversely oriented molecules of the title compound, C15H9BF2O3, form stacks along the a axis via π–π interactions between parallel phenylchromenium fragments. Linked by a network of C—H...F interactions, the stacks form layers in the ac plane that are dispersively stabilized in the crystal structure. Two F atoms bonded to the B atom are located in the plane perpendicular to the planar skeleton of the molecule made rigid by two intramolecular C—H...O interactions.
