 Title    Neue Oxogermanate(IV) der schweren Alkalimetalle. Synthesen und Kristallstrukturen New Oxogermanates(IV) of the Heavy Alkaline Metals. Preparation and Crystal Structure  
 Abstract    The new germanates(IV) were synthesized via reaction of GeC>2 with AO2 (A=K, Rb, Cs) and the elemental alkaline metals and their crystal structures have been determined from single crystal X-ray data. ß-K^GeOi / Rh+GeC^ (monoclinic, P 2 \/c , a = 1047.6(3)/1103.2(2), b = 646.5(1)/673.3(1), c = 1048.1(3)/1084.5(2) pm, ß = 112.291(5) / 112.676(4)°, Z = 4) and CsioGe209 (monoclinic, P 2 \/c , a = 1293.7(2), b = 1148.6(2), c = 1926.4(2) pm, ß = 128.05(8)°, Z = 4) contain isolated, AöGe309 (A = Rb / Cs: monoclinic, P 2 \/c , a = 663.0(1) / 696.3(2), b = 1346.8(2) / 1403.1(3), c = 1666.6(2) / 1742.8(6) pm, ß = 107.47(2) / 107.88(2)°, Z = 2) cyclotrigermanate ions. In Cs3AlGe207 (monoclinic, C 2/c, a = 961.5(2), b = 1719.7(2), c = 761.7(1) pm, ß =126.5(1)°, Z = 4) digermanate ions are connected via [AIO4 ] tetrahedra to form ribbons.
