    Description / Table of Contents: Lattice Constants and Ionic Radii of Pyrochlores CsMIIMIIIF6From observed lattice constants a0 of 30 cubic pyrochlores CsMIIMIIIF6 (MII = Mg, Ni, Cu, Zn, Co, Mn; MIII = Ga, Cr, Fe, V, Ti) balanced values ac were calculated, which deviate in average less than 0.1% from the observed ones. Radii rc of the M(II) and M(III) ions are evaluated from the balanced values ac by means of an empiric equation; they reproduce the lattice constants a0 equally well. By analogy derived radii rII and rIII from additional pyrochlores CsMIIMIIIF6 are given and discussed in comparison with tabulated radii and observed M—F distances.
    Notes: Aus den beobachteten Gitterkonstanten a0 von 30 kubischen Pyrochloren CsMIIMIIIF6 (MII = Mg, Ni, Cu, Zn, Co, Mn; MIII = Ga, Cr, Fe, V, Ti) werden Ausgleichswerte ac gebildet, die im Mittel weniger als 0,1% von den Beobachtungsgrößen abweichen. Aus den Ausgleichswerten ac werden mit Hilfe einer empirischen Beziehung Radien rc für die M(II)- und M(III)-Ionen abgeleitet, mit denen die Gitterkonstanten a0 mit entsprechender Genauigkeit reproduzierbar sind. Analog aus weiteren Pyrochloren CsMIIMIIIF6 ermittelte Radien rII und rIII werden mitgeteilt und im Vergleich mit tabellierten Radien und beobachteten M—F-Abständen diskutiert.
