Sumario:The crystal structures are reported of the 6,6-di­fluoro-6H-dibenzo[c,e][1,2]oxaborinin-6-ide (or 9,9-di­fluoro-10-oxa-9-boraphenanthren-9-ide) anion with two different cations, namely, potassium 6,6-di­fluoro-6H-dibenzo[c,e][1,2]oxaborinin-6-ide, K(+)·C(12)H(8)BF(2)O(−), (II), featuring a polymeric structure, and bis­(tetra­phenyl­phospho­nium) bis­(6,6-di­fluoro-6H-dibenzo[c,e][1,2]oxaborinin-6-ide) aceto­nitrile tris­olvate, 2C(24)H(20)P(+)·2C(12)H(8)BF(2)O(−)·3CH(3)CN, (III), which is composed of discrete cations, anions and aceto­nitrile solvent mol­ecules 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.
