Pure H3OCd(SbF6)(Sb2F11)(2) is prepared by the reaction of CdO with nSbF(5) (n >= 5) or by reaction of H3OSbF6, Cd(SbF6)(2) and nSbF(5) (n >= 2) in anhydrous hydrogen fluoride. H3OCd(SbF6)(Sb2F11)(2) crystallizes in the monoclinic space group P2(1)/a (No. 14) with a = 986.1(4) pm, b = 1257.3(5) pm, c = 1826.8.4(8) pm, beta = 98.062(4)degrees and Z = 4.



Reaction of CdO with SbF5 (n <= 3) in anhydrous HF yields only a mixture of H3OSbF6 and Cd(SbF6)(2). No reactions were observed also when different ratios of H3OSbF6 and Cd(SbF6)(2) were used as starting materials. However, the re-crystallization of these mixtures yielded single crystals of new phases: (H3O)(2)Cd(SbF6)(3)(Sb2F11) and (H3O)(2)Cd2F(SbF6)(5). The former crystallizes in the orthorhombic Pcca space group (No. 54) with a = 2189(2) pm, b = 1121.2(8) pm, c = 1894(1) pm and Z = 8 and the latter in the monoclinic P2(1)/a space group a = 1019(4) pm, b = 1112(1) pm, c = 1147(1) pm, beta = 107.81(1)degrees and Z = 2. The attempt to prepare single crystals of Cd(SbF6)(2) resulted in the preparation of few single crystals of (H3O)[Cd(HF)](4)(SbF6)(9), which crystallizes in the monoclinic space group C2/c (No. 15) with a = 2087(3) pm, b = 1021(5) pm, c = 2112(2) pm, beta = 99.36(2)degrees and Z = 4.
