- Аннотация: Subsolidus phase relations in the Cs2MoO4-ZnMoO4-Zr(MoO4)(2) system were determined and two new compounds, Cs2ZnZr(MoO4)4 and Cs(2)ZnZr2(MoO4)(6), were obtained. The structure of Cs2ZnZr(MoO4)(4) (a=5.7919(1) angstrom, c=8.0490(3) A; space group P (3) over bar m1; Z=0.5; R=0.0149) belongs to the layered glaserite-like KAl(MoO4)(2) structure type where the octahedral Al3+ positions are statistically occupied by 0.5 Zn2+ + 0.5 Zr4+. The second triple molybdate, Cs(2)ZnZr2(MoO4)(6) (a=13.366(1) angstrom, c=12.253(3) angstrom, space group kg, Z=3, R=0.0324), is isostructural to Cs2MnZr2(MoO4)6 and Cs2M2Zr(MoO4)(6) (M=Al, Fe) and contains a mixed 3D framework built of MoO4 tetrahedra and (Zn, Zr)O-6 octahedra sharing common vertices. Cesium cations are located in large channels of the framework. The latter compound undergoes a first-order phase transition at 723 K with considerable increasing its ionic conductivity.
