We examined low-temperature synthetic route based on the amorphous nature of giant species to succeed to prepare Cs blue bronze (Cs{sub 0.3}MoO{sub 3}), which has never obtained by usual high-temperature methods, at ca. 680K. Solid solutions (K{sub 1-x}Rb{sub x}){sub 0.28}MoO{sub 3} and (Li{sub 1-x}Na{sub x}){sub 0.9}Mo{sub 6}O{sub 17} were also obtained at lower temperatures (ca. 670K). For the latter system consisting of non-isostructural end members, Li{sub 0.9}Mo{sub 6}O{sub 17}-structure type solid solution was formed even when 0.25<x<0.70, unlike the case by the usual high-temperature methods. Metastable mixed oxides Ln{sub 2}Mo{sub 3}O{sub 9} (Ln=La, Gd) were obtained, but not as single phases.
