Abstract
Abstract Synthesis, structural characterization and chemical bonding peculiarities of two new quaternary selenides of the Tl4Sb8Sn5Se24 and Tl5Sb2Sn4Se14−x (x = 0.5) are reported. The crystal structures of these compounds were determined by single crystal X-ray diffraction analysis. The Tl4Sb8Sn5Se24 phase is a new structure type and crystallizes in the triclinic P 1̅ space group (a = 7.9061(13) Å, b = 13.9035(16) Å, c = 21.4665(17) Å, α = 80.058(8)°, β = 84.727(10)°, γ = 73.542(12)°, wR 2 = 0.0258, 8200 F 2 values, 373 variables). The Tl5Sb2Sn4Se14−x (x = 0.5) phase represents a new structure type with a tetragonal unit cell (P 4/mbm, a = 8.1570(10) Å, c = 21.946(3) Å, wR 2 = 0.0346, 1953 F 2 values, 44 variables). Crystallographic analysis together with linear muffin-tin orbital band structure calculations reveals that both structures we conform to the concept of Zintl-Klemm and exhibit semiconductor properties.
