Abstract/Summary:
The previously known adduct XeF(,2).AsF(,5) was re-examined. Based on Raman and structural information, the compound was assessed to be intermediate between the salt formulation (FXe)('+)AsF(,6)('-) and the fluorine bridged molecular adduct.; A series of graphite fluorosulfates were prepared, using as the oxidizing agent S(,2)O(,6)F(,2), and the effects of incorporating varying amounts of fluorosulfonic acid were studied. Physical data indicated that the S(,2)O(,6)F(,2) was incorporated as SO(,3)F('-), and the HSO(,3)F was bound tightly, probably due to hydrogen bonding. The c-spacings of HSO(,3)F containing materials were larger than those of acid free materials, and the influences of charging, guest size and guest orientation were examined.; X-ray diffractometer studies of graphite "slabs" intercalated with SO(,3)F/HSO(,3)F and IrF(,6) indicated structures consistent with the characterization of these materials as containing tetrahedral SO(,3)F and octahedral IrF(,6).; Boron nitride reacted with S(,2)O(,6)F(,2) to yield a deep blue, conducting intercalation compound. This material was in many respects similar to its graphite analog, but chemically more labile.
