“…The uncertainty in V6 is again large, the minimal value being 174 cm -I from the estimate by Aleksanrovskava et al 32 and the maximal value being 252 cm -1, reported by Mohammed and Sherman,35 for SbF 6 isolated in a rubidium bromide crystal at a site symmetry of D 2h . The present estimate, v6 -vs/2112 -197 Clll-1 , is cOIlsisleIll wilh lhe assignment of Bougon et al 32 Most of the other frequencies reported 29 ,31-33 agree with the set of Bougon et al,30 also. These alternative values of V6 could produce a variation of 8.5 J K-I mol-I in the entropy, independent of the temperature, and corresponding changes in the other thermodynamic functions.…”

The standard thennodynamic functions (C;, So, HO and (Go-H8)/n at 100 to 1000 K of 24 polyatomic gaseous ions are reported, based on structural and spectroscopic data from the literature. These ions supplement the 130 ions previously studied and are: zirconyl, hydrotelluride, amide, selenocyamite, tellurocyanate, orthoborate, metaphosphate, arsenite, orthosilicate, tetrachloropalladate(II), tetrabromopalladate(II), tetrachloroplatinate(II), tetrabromoplatinate(II), hexafiuorophosphate, hexafiuoroarsenate, hexafiuoroantimonate, hexabromoplatinate(IV), tetracyanonickelate, tetracyanomercurate, octacyanomolybdate(IV), sulfamate, benzoate, guanidinium, and glycine as cation, zwitterion, and anion.

“…The nitrosonium and nitronium salts of weakly coordinating anions (WCA) are useful oxidants in synthetic chemistry yielding WCA salts of oxidized species [4,5,6] . Numerous ionic NO + and NO 2 + salts of the type AM III F 4 , A 3 M III F 6 , A 2 M IV F 6 , AM V MF 6 , AM VI MF 7 , A 2 M VI F 8 (A=NO + , NO 2 + ) are known [7,8,9,10,11,12,13] . They can be prepared by a reaction of NOF [14] or NO 2 F, respectively, with corresponding binary fluorides.…”

Reaction between NOSbF6 and Cu(SbF6)2 in aHF yielded NOCu(SbF6)3. In the presence of H3OSbF6, single crystals of (H3O)0.2(NO)0.8Cu(SbF6)3 were grown from a saturated aHF solution. Both salts are isotypic and crystallize in the orthorhombic space group Pnma (No. 62) at 200 K. The main feature of their crystal structures are rings of CuF6 octahedra sharing apexes with SbF6 octahedra connected into 3‐D network. Single charged cations are located inside the cavities. Reaction between 0.25NOSbF6, 0.75NO2SbF6 and Cu(SbF6)2 in aHF yielded (NO)0.25(NO2)0.75Cu(SbF6)3 upon the crystallization. It crystallizes in the cubic space group Im3‾ (No. 204) at 200 K. Subsequent experiments with M(SbF6)2 (M=Cu, Zn) showed that, when the NO+ cations are partially or completely replaced by H3O+, the grown crystals of (H3O)0.125(NO)0.125(NO2)0.75Zn(SbF6)3 and (H3O)0.25(NO2)0.75M(SbF6)3 (M=Cu, Zn) are isotypic to (NO)0.25(NO2)0.75Cu(SbF6)3. Crystal structure of the latter demonstrates similar 3‐D structural motif as observed for the NOCu(SbF6)3 salt. The crystal structures of (H3O)0.64(NO2)0.36CuF(SbF6)2 and [Cu(H2O)6](SbF6)2 were also determined. Crystallizations of NOSbF6/O2SbF6 were carried out in aHF in different molar ratios. The crystal structure determinations of grown single crystals showed that they have the composition (NO)x(O2)1‐xSbF6 (x=0.17, 0.55 0.75) indicating that most likely all phases with x=0–1 exist. They are isotypic to NOSbF6.

“…The complex structure of ASb 2 F 11 (A = Ag, K) reveals three crystallographically non-equivalent [Sb 2 F 11 ] À anions, highly distorted from the ideal D 4h or D 4d symmetries, which differ only in the angular orientation of the SbF 5 units relative to each other [65]. There are also three crystallographically nonequivalent A + (A = Ag, K) cations in the crystal structure of the corresponding [Sb 2 F 11 ] À salts.…”
