Abstract: | New Elpasolithes with CoIII: Cs2KCoF6, Rb2KCoF6, Rb2NaCoF6 (with a Notice on Cs2NaCoF6) New prepared are the compounds Cs2KCoF6 (a = 8.979 Å), Rb2KCoF6 (a = 8.809 Å), Rb2NaCoF6 (a = 8.421 Å), all cubic Elpasolithes, as well as Cs2NaCoF6 (Cs2NaCrF6?type, hexagonal with a = 6.23, c = 30.32 Å) all of light blue colour. Cs2KCoF6 (72.7–299.7 K) and Rb2KCoF6 (71.4–298.0 K) have been measured magnetically. The Madelung Part of Lattice Energy (MAPLE) is calculated and discussed. |
