Neues über Hexafluoromanganate(IV). MIIMnF6 mit M=Mg,Ca, Zn,Cd, Hg,Ni, Cu,Ag

Newly obtained are NiMnF₆ (ochre-yellow) and ZnMnF₆ (orangeyellow), both VF₃-type a = 4.91₀, c = 13.16₉ Å (Ni); a = 4.96₆, c = 13.29₃ Å (Zn)], as well as CdMnF₆ (yellow) and HgMnF₆ (orange), both of LiSbF₆ type a = 5.08₇, c = 14.00₇ Å (Cd); a = 5.08₄, c = 14.12₅ Å (Hg)]. CuMnF₆ (copper-red) and AgMnF₆ (blackbrown) show complicated powder diagrams. MgMnF₆ and CaMnF₆ belong to the LiAbF₆ type, too Guinier-photographs].
