In the process of studying the system Tl 2 MoO 4 -In 2 (MoO 4 ) 3 -Hf(MoO 4 ) 2 , a new thallium indium hafnium molybdate was found. The crystal structure of the molybdate Tl 5 InHf(MoO 4 ) 6 was determined in the centrosymmetric space group R c (a = 10.63893 (5) Å, c = 38.1447(3) Å; V = 3739.04 (4) Å 3 , Z = 6). The structure is a framework consisting and contains alternating mixed (Hf,In)O 6 octahedra connected by MoO 4 tetrahedra. The structure is a three-dimensional framework consisting of alternating (Hf,Fe)O 6 -octahedra connected by МоО 4 -tetrahedra. Each octahedron has common vertices with tetrahedra. The atoms arranged in this way form channels extended along with the a and b axes, in which thallium atoms are located. The conductivity behavior of Tl 5 InHf(MoO 4 ) 6 ceramics was studied in the temperature range from 300 K to 870 K. The conductivity of the heavy cations of thallium is activated with increasing temperature.
