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.
