[Tl₇]^7- Clusters in Mixed Alkali Metal Thallides Cs_7.29K_5.71Tl₁₃ and Cs_3.45K_3.55Tl₇.

ABSTRACT: Investigations in the ternary system Cs-K-Tl resulted in the unexpected formation of new ternary thallides Cs_7.29K_5.71Tl₁₃ and Cs_3.45K_3.55Tl₇. Single crystal X-ray structure analyses of both compounds reveal the presence of isolated Tl cluster units. Cs_7.29K_5.71Tl₁₃ crystallizes in the monoclinic space group C2/c (a = 30.7792(9) Å, b = 11.000(2) Å, c = 14.0291(4) Å, β = 112.676(4)°, Z = 4) and contains [Tl₆]^6- and [Tl₇]^7- clusters as thallium subunits. Cs_3.45K_3.55Tl₇ crystallizes in the tetragonal space group I4₁/a (a = 13.6177(2) Å, c =
