    Description / Table of Contents: On Oxorhodates of Alkali Metals: β-LiRhO2We prepared hitherto unknown β-LiRhO2 in form of black, cubic single crystals, O4-F4132, a = 841.27(6) pm, Z = 16. For a first time in case of such metal oxides we find one of the possible variants of order between the NaCl-type with random distribution and the complete ordered types like α-NaFeO2 as a single crystal (four-circle-diffractometer PW 1100, AgKα, 100 von 109 I0(hkl), R = 9.10%, Rw = 5.46%). The Madelung Part of Lattice Energy, MAPLE, and Effective Coordination Numbers, ECoN, these via Mean Fictive Ionic Radii, MEFIR, were calculated and discussed.
    Notes: Neu dargestellt wurde in Form schwarzer, kubischer Einkristalle β-LiRhO2, O4-F4132, a = 841,27(6) pm, Z = 16. Erstmals wird eine der möglichen Ordnungsvarianten zwischen NaCl-Typ mit statistischer Verteilung und völlig geordneten Varianten, z. B. α-NaFeO2-Typ, durch Einkristalldaten bei derartigen Oxometallaten mit Alkalimetallen belegt (Vierkreisdiffraktometer PW 1100, AgKα, 100 von 109 I0(hkl), R = 9,10%, Rw = 5,46%). Der Madelunganteil der Gitterenergie, MAPLE, sowie Effektive Koordinationszahlen, ECoN, diese über Mittlere Fiktive Ionenradien, MEFIR, berechnet, werden angegeben und diskutiert.
