 Title    Über Oxoplumbate(rV) Die Kristallstruktur von TT-Li2Pb03 [1] On Oxoplumbates(IV) The Crystal Structure of LT-Li2Pb03 [1]  
 Abstract    For the first time single crystals of LT-Li2Pb03 have been prepared by decomposition of K2Li6[Pb20s] [incompletely closed Ag cylinders, sealed in Supremax-glass ampoule, vacuum, 690°C, 100 d]. The structure determination [533Io(hkl); four-circle-diffractometer PW1100, co -scan, Mo -Ka, R = 4,86%, Rw = 4,93% confirms space group C2/c with a = 544.52(7), 6 = 926.12(7), c = 547,56(8) pm, ß = 111.216(13)°, Z = 4, drö = 6.94 g-cm" 3 , dpyk = 6.89 g • cm -3 . The NaCl-type structure variant is characterized by alternating layers of Li(2)+ and Li(l)+/Pb 4+ ~ cations. All atoms have octahedral coordination. The Madelung Part of Lattice Energy, MAPLE, Effective Coordination Numbers, ECoN, these via Mean Fictive Ionic Radii, MEFIR, are calculated.
