Erstmals dargestellt und anhand von Einkristallen röntgenographisch untersucht wurden die intensiv grünen Verbindungen AgM   3 II M   3 IV F 20 (M II = Cd, Ca, Hg; M IV = Zr, Hf). Sie kristallisieren alle in der Raumgruppe P6 3 /m‐C   6h 2(Nr. 176) mit a = 1052,0(2) pm, c = 828,6(2) pm (AgCd 3 Zr 3 F 20 ), a = 1048,0(2) pm, c = 832,6(3) pm (AgCd 3 Hf 3 F 20 ), a = 1059,4(2) pm, c = 841,0(3) pm (AgCa 3 Zr 3 F 20 ), a = 1053,7(2) pm, c = 830,6(3) pm (AgCa 3 Hf 3 F 20 ), a = 1058,9(3) pm, c = 832,6(4) pm (AgHg 3 Zr 3 F 20 ), a = 1056,9(2) pm, c = 833,0(3) pm (AgHg 3 Hf 3 F 20 ), Z = 2.
