In the crystal, the inversely oriented mol-ecules of the title compound, C(15)H(9)BF(2)O(3), 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. ...[more]
