    Description / Table of Contents: On Fluoroniccolates(III): Cs2KNiF6, Cs2NaNiF6, Rb2KNiF6, Rb2NaNiF6, and K2NaNiF6New prepared are the compounds Cs2KNiF6 (a = 8.936 Å), RB2KNiF6 (a = 8.734 Å), Rb2NaNiF6 (a = 8.376 Å), K2NaNiF6 (a = 8.211 Å) all cubic Elpasolithes, as well as Cs2NaNiF6 (Cs2NaCrF6-type, hexagonal with a = 6.20 Å, c = 30.03 Å) all of violet blue colour. The magnetic measurements on Cs2KNiF6 and K3NiF6 indicate the existence of thermal equilibrium between low-spin and high-spin form. the MADELUNG Part of Lattice Energy, MAPLE, is calculated and discussed.
    Notes: Neu dargestellt wurden Cs2KNiF6 (a = 8,936 Å), Rb2KNiF6 (a = 8,734 Å), Rb2NaNiF6 (a = 8,376 Å), K2NaNiF6 (a = 8,211 Å), alle kubische Elpasolith-Vertreter, sowie Cs2NaNiF6 (Cs2NaNiF6-Typ, hexagonal mit a = 6,20 Å, c = 30,03 Å) als fliederfarbene Pulver. Magnetische Messungen an Cs2KNiF6 und K3NiF6 entsprechen dem Vorliegen eines thermischen Gleichgewichtes zwischen Low- und High-Spin-Form. Der MADELUNG-Anteil der Gitterenergie, MAPLE, wird berechnet und diskutiert.
