Ta3(Te2)6, Mr = 2074. 04, tetragonal, P4/ncc, a = 9. 204(1) A , c=20,401(8) A, V=1728. 3 A 3, Z = 4, Dc = 7. 97g/cm3, λ(MoKa) = 0. 71073 A . μ= 386, 3cm-1,F(000) = 3372, T= 296K , R= 0. 027, Rw = 0, 029 for 493 observed unique reflections. The structure is composed of infinite [TaTe4] chains along the e axis. In these chains, the Ta sequences distort in such a way that linear Ta, clusters are formed.
