fluorine atoms. Negative charge of the anions is compensated by single charged cations. Crystal structure of α-NH4Sb2F11 demonstrates similar motif as in β-phase but with slightly re-arranged N―H… F hydrogen bonds. In the 100−296 K range, only rhombohedral phase was observed for NH4SbF6 (rhombohedral space group R 3¯, No. 148) with a = b = 7.5961(9) Å, c = 7.7176(9) Å, α = β = 90°, γ = 120°, V = 385
RbSb 2 F 11,TlSb 2 F 11,O 2 Sb 2 F 11和β- NH 4 Sb 2 F 11盐的晶体结构是同型的,并且在正交晶空间群Cmc2 1(第36号)中结晶。
