Solubility of salts in organic solvents is a function of both the cation and the anion.  The solubility of cations in organic solvents can be enhanced when the anion is lipophilic. Similarly, the solubility of anions in organic solvents is enhanced with lipophilic cations.  The most common lipophilic cations are quaternary ammonium cations, called "quat salts".
Many cationic organometallic complexes are isolated with inert, noncoordinating counterions.  Ferrocenium tetrafluoroborate is one such example.
