Zur Kenntnis der Hexafluororhodate(III): Über Cs2K[RhF6], Rb2K[RhF6], K2Na[RhF6], Rb2Na[RhF6] und Tl2Na[RhF6]

On the Knowledge of Hexafluororhodates(III): Cs₂KRhF₆], Rb₂KRhF₆], K₂NaRhF₆], Rb₂NaRhF₆] and Tl₂NaRhF₆]. New prepared are the compounds Cs₂KRhF₆ (a = 9.04₉ Å), Rb₂NaRhF₆ (a = 8.49₂ Å), Rb₂KRhF₆ (a = 8.87₆ Å), K₂NaRhF₆ (a = 8.36₂ Å) and Tl₂NaRhF₆ (a = 8.52₆ Å), all cubic Elpasoliths of pink colour. The Madelung-Part of lattice energy, MAPLE, is calculated and discussed.
