Fluoride ion donor ability of binary fluorides towards the Lewis acids AsF5 and SbF5

Crystal Growth and Crystal Structures of Gold(V) Compounds: Cu(AuF6)2, Ag(AuF6)2, and O2(CuF)3(AuF6)4 ⋅ HF

“…[d] Corresponding M(AsF 6 ) 2 salts (M=Cr, Fe, Cu, Zn) do not exist. Only products with lower content of AsF 5 have been isolated at room temperature [36] . [e] Based on XRPD and vibrational spectroscopy data, Cd and Hg salts are isotypic to Mn(AsF 6 ) 2 (Type IV ) [35] .…”

“…Based on Raman spectroscopy data, the corresponding Cr salt and a modification of the Fe salt are isotypic with M(SbF 6 ) 2 (M=Mn, Cu, Pd, Ag, Au) salts (Type I ) [17] . [j] The synthesis has been reported [16,36] . Only the crystal structure of the HF‐containing salt Hg(HF)(SbF 6 ) 2 (not isotypic with the analogous AsF 6 − salt) is known [39] .…”

“…Since there are three different modifications of Fe(SbF 6 ) 2 (Type I , II and III ), it is not impossible that other modifications exist for Cu(SbF 6 ) 2 . There is no structural information about M(SbF 6 ) 2 (M=Cd, [16] Hg [36] ) in the literature. Only the crystal structure of the HF‐containing Hg(HF)(SbF 6 ) 2 salt is known [39] …”

“…Only products with lower content of AsF 5 have been isolated at room temperature. [36] [e] Based on XRPD and vibrational spectroscopy data, Cd and Hg salts are isotypic to Mn(AsF 6 ) 2 (Type IV). [35] Only crystal structures of HF-containing salts are known as Hg(HF) 2 (AsF 6 ) 2 and M(HF)(AsF 6 ) 2 (M = Cd, Hg; isotypic).…”

“…[17] [j] The synthesis has been reported. [16,36] Only the crystal structure of the HF-containing salt Hg(HF)(SbF 6 ) 2 (not isotypic with the analogous AsF 6 À salt) is known. [39] [l] According to unit cell parameters, Ag(NbF 6 ) 2 is isotypic to Ag(TaF 6 ) 2 .…”
