| Abstract: | An Oxomanganate(V) of New Type: K11{LiOMnO3]}4 By heating of well ground mixtures of the oxides K2O2, LiMnO4, K:Mn = 2.2:1, Ag-tube, 580°C, 30 d] blue-green tetragonal single crystals of K11{LiOMnO3]4} have been prepared for the first time: space group I4 2m; a = 787,18(7) pm, c = 1750.9(3) pm. The structure was determined by four-circle-diffractometer data MoKα , 1236 from 1303 Io(h kl), R = 3.9%, Rw = 3.1%], parameters see text. The Madelung Part of Lattice Energy, MAPLE, and the Effective Coordination Numbers, ECoN, these via Mean Fictive Ionic Radii, MEFIR, have been calculated. |
