The special guest : In the host–guest chemistry of dinuclear complexes that contain the 9 H ‐fluorene‐9,9′‐dimethanediphenylphosphinite ligand the synergy between the phenyl groups and the axial fluorene moiety leads to the formation of molecular cavities that have selective steric affinity for the anions BF 4 − or PF 6 − (see picture). An unprecedented M⋅⋅⋅F(PF 5 )⋅⋅⋅M bridging coordination mode of PF 6 − has now been established.
