| Abstract: | A New Oxomanganate (II): KLiMnO2 For the first time, KLiMnO2 has been prepared from the binary oxides (640°C, 17 d, Ni? or Ag-cylinders) in form of orange-coloured single crystals. The crystal structure (a = 11.085, b = 3.389, c = 8.357 Å, β = 120.67°, Space-Group C2/m, 4-circlediffractometer, MoKα, 458 I0 (hkl), R = 4.87%) corresponds to that of KLiZnO2. Both oxides represent a new formula type A[(TO)n] with n = 2 and K[7] Li[4] Mn[4] O2. Effective Coordination Numbers, ECoN, and the Madelung Part of Lattice Energy, MAPLE, are calculated and discussed. |
