Abstract

The compound Cs₂Ag₂ZrTe₄ was synthesized through reaction of the elements in a Cs₂Te₃/Te flux at 900 C. The compound crystallizes in the orthorhombic space group D₂ ⁶—C222 with two formula units in a cell of dimensions a = 6.508 (7) Å, b = 15.164 (16) Å, c = 6.518 (6) Å, V = 643.2 (11) Å³ at 113 K. The structure has been refined to a value of R_W (F_o ²) of 0.111 for 1138 data and 24 variables; the value of R₁ (on F) is 0.053. The Cs₂-Ag₂ZrTe₄ structure comprises two-dimensional slabs of Ag- and Zr-centered tetrahedra separated by Cs⁺ cations. This appears to be the first example of the tetrahedral coordination of Zr⁴⁺ by chalcogen anions in a solid-state compound.
