H3OM(SbF6)3 (M = Mg, Co, Ni Fe, Cu and Zn) compounds crystallize isotypically. Slow crystallizations of H3OSbF6/M(SbF6)2 (M = Mn, Pd, Cd) mixtures result in a new type of compounds, i.e. (H3O)3M(SbF6)5. Crystal structure of each (H3O)3M(SbF6)5 (M = Mn, Pd, Cd) represents a unique case. Discrete [CrIV(SbF6)6]2− units are present in (H3O)3[CrIV(SbF6)6](Sb2F11)·HF.
