The crystal structures are reported of the 6,6-di-fluoro-6-dibenzo[,][1,2]oxaborinin-6-ide (or 9,9-di-fluoro-10-oxa-9-boraphenanthren-9-ide) anion with two different cations, namely, potassium 6,6-di-fluoro-6-dibenzo[,][1,2]oxaborinin-6-ide, K·CHBFO, (), featuring a polymeric structure, and bis-(tetra-phenyl-phospho-nium) bis-(6,6-di-fluoro-6-dibenzo[,][1,2]oxaborinin-6-ide) aceto-nitrile tris-olvate, 2CHP·2CHBFO·3CHCN, (), which is composed of discrete cations, anions and aceto-nitrile solvent mol-ecules linked by C-H⋯O, C-H⋯N and C-H⋯F hydrogen bonds. There are only minor differences in the geometrical parameters of the anions in these structures.
