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 RW (Fo 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.
