Abstract:
By heating of a well-ground mixture of the binary oxides KO0.55, Li2O and GeO2 (K:Li:Ge = 6.1:2.2:2; Ni-tube; 600-degrees-C; 49 d) we obtained for the first time single crystals of K5{Li[Ge2O7]}. This 'litho-digermanate' represents a completely new type of structure: monoclinic, space group P2(1)/c, a = 624.9(2) pm, b = 1586.6(8) pm; c = 1058.3(6) pm and beta = 109.38(4)degrees; Guinier-Simon data, Z = 4. The structure was solved by four-circle diffractometer data [Siemens AED II, Mo-KaalphaBAR; 2872 I(o)(hkl); R = 4.5%, R(w) = 3.3%], parameters see text. The Madelung Part of Lattice Energy, MAPLE, and Effective Coordination Numbers, ECoN, these calculated via Mean Fictive Ionic Radii, MEFIR, as well as charge distribution CHARDI, are calculated and discussed.
