Abstract

Earth metals I 2000The Suboxometallates A9MO4 (A: Rb, Cs; M: Al, Ga, In, Fe, Sc). -Single crystals of A 9 MO 4 (A: Rb, Cs; M: Al, Ga, In, Fe, Sc) are prepared from mixtures of M 2 O 3 , A, and A2O in a ratio of 1:5:8 (Ta crucible, 300°C, 2 h). The A9MO4 compounds and (Rb0.57Cs0.43)Cs8GaO4, (Rb0.87Cs0.13)Cs8InO4, Cs9(Al0.51In0.49)O4, and Cs9(Sc0.68In0.32)O4 crystallize in the tetragonal space group I4/mcm with Z = 4 (single crystal XRD) and contain ortho-oxometallate(III) anions in a metallic matrix. -(HOCH*, C.; BENDER, J.; WOHLFARTH, A.; SIMON, A.
