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

Abstract

In the crystal, the inversely oriented mol-ecules of the title compound, C15H9BF2O3, form stacks along the a axis via π-π inter-actions between parallel phenyl-chromenium fragments. Linked by a network of C - H⋯F inter-actions, 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 mol-ecule made rigid by two intra-molecular C - H⋯O inter-actions.
