Abstract: | The First Oxide with the Formula Type K5[MO4]: K5[TlO4] Light yellow powder and pale yellow transparent single crystals of K5[TlO4] were newly prepared from mixtures of binary oxides (K2O/Tl2O3) preheated and levigated several times [closed Ag-cylinder, 580°C, 24 h and 600°C, 20 d]. Space group Pbca with a = 1170.4(3), b = 686.1(1), c = 2079.2(5) pm, Z = 8 [four-circle-diffraktometer data, 997 I0(hkl), R = 7.87%, Rw = 5.63%, MoKα] (parameter s. text). The crystal structure belongs to the Na5[GaO4] type. Structural aspects, ECoN and MAPLE are discussed. |
