Description / Table of Contents:
A New Oxomanganate (II): KLiMnO2For 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.
Notes:
Neu dargestellt wurde KLiMnO2 aus den binären Oxiden (640°C, 17d,Ni- bzw. Ag-Bömbchen) in Form orangefarbener Einkristalle. Die Kristallstruktur (a = 11,085, b = 3,389, c = 8,357 Å, β = 120,67°, R. Gr. C2/m, Vierkreisdiffraktometer, MoKα, 458 I0 (hkl), R = 4,87%) entspricht der von KLiZnO2. Es liegt ein Oxid des neuen Formeltyps A[(TO)n] mit n = 2 vor, entsprechend K[7] Li[4] Mn[4] O2. Effektive Koordinationszahlen, ECoN, und der Madelunganteil der Gitterenergie, MAPLE, werden berechnet und diskutiert.
