Synthese und Struktur von RbHfF5, Rb2Zr3F12O und Rb2Hf3F12O — zwei Oxidfluoride mit zentraler trigonal-planarer [M3O]-Gruppe
Abstract
deFarbloses RbHfF5 kristallisiert isotyp zu (NH4)ZrF5 und TlHfF5 monoklin, Raumgruppe P21/c - C2h (Nr. 14) mit a = 776.6, b = 789.6, c = 789.8 pm und β = 120.52°. Ebenfalls farbloses Rb2Zr3F12O kristallisiert trigonal in R3¯m — D3d (Nr. 166), mit a = 771.9 und c = 2963.0 pm, isotyp hierzu ist Rb2Hf3F12O mit a = 769.2 pm und c = 2986.1 pm. Beide Verbindungen sind isotyp zu Tl2Zr3F12O.

enSynthesis and Structure of RbHfF5, Rb2Zr3F12O and Rb2Hf3F12O — two Oxydefluorides with Central Trigonal-plane [M3O] Group
Colorless RbHfF5 crystallizes isotypic with (NH4)ZrF5 and TlHfF5 monoclinic, space group P21/c - C2h (No. 14) with a = 776.6, b = 789.6, c = 789.8 pm, and β = 120.52°. Also colorless Rb2Zr3F12O crystallizes trigonal, space group R3¯m — D3d (No. 166), with a = 771.9 and c = 2963.0 pm, isotypic is Rb2Hf3F12O with a = 769.2 pm and c = 2986.1 pm. Both compounds are isotypic with Tl2Zr3F12O.
