Description / Table of Contents:
On Li2[CuO2]At the first time single crystals of Li2[CuO2] are prepared by exchange reaction. The crystal structure (I mmm) with a = 365.4(0), b = 285.9(0), c = 937.4(0) pm, Z = 2, dx = 3.73 g/cm3, dpyk = 3.67 g/cm3 was refined (four-circle-diffractometer data PW 1100, 343 Io(hkl), MoKα, R = 0.046, Rw = 0.041). The characteristic structure element is the planar chain \documentclass{article}\pagestyle{empty}\begin{document}$ {}_\infty ^1 \left[{{\rm CuO}_{4/2}} \right]^{2 -} $\end{document}. The Madelung Part of Lattice Energy, MAPLE, Effective Coordination Numbers, ECoN, these via Mean Fictive Ionic Radii, MEFIR, are calculated.
Notes:
Einkristalle von Li2[CuO2] wurden erstmals durch „Austauschreaktion“ dargestellt und die Kristallstruktur (I mmm) mit a = 365,4(0), b = 285,9(0), c = 937,4(0) pm, Z = 2, drö = 3,73 g/cm3, dpyk = 3,67 g/cm3 aufgeklärt (Vierkreisdiffraktometerdaten, PW 1100, 343 Io(hkl), MoKα, R = 0,046, Rw = 0,041). Das charakteristische Strukturelement ist die planare Ketve \documentclass{article}\pagestyle{empty}\begin{document}$ {}_\infty ^1 \left[{{\rm CuO}_{4/2}} \right]^{2 -} $\end{document}. Der Madelunganteil der Gitterenergie, MAPLE, Effektive Koordinationszahlen, ECoN, diese über Mittlere Fiktive Ionenradien, MEFIR, werden berechnet.
