Eight binary salts that pair triazolium(1+), imidazolium(1+), pyrimidinium(1+), or purinium(1+) cations with the icosahedral closo-dodecafluorododecaborate(2-) anion (B12F12 2-) were synthesized using open-air benchtop metathesis reactions in water or acetonitrile. The scale of the reactions varied from just milligrams to nearly one gram of the K2B12F12 starting material. Other reaction conditions, the scope of the reaction, and the solubilities for the new salts are discussed. Five [heterocyclium]2[B12F12] salts, which were obtained in yields ranging from 84% to 99%, displayed significantly higher densities than the corresponding previously reported analogous [heterocyclium]2[B12H12] and [heterocyclium][CB11H12] salts. A ninth high-d. salt consisted of B12F12 2- paired with a complex Ag4(triazole)8 4+ cation. The structures of eight of the nine new compounds were determined by single-crystal x-ray diffraction anal. The d. of five [heterocyclium]2[B12F12] salts was found to increase approx. linearly as the distance between the five-membered-ring heterocyclium(1+) cation centroids decreased. This work demonstrates addnl. flexibility for the rational design of ionic structures with predictable properties, which will ultimately permit the tailoring of ingredient-response behavior.
