Quaternary chalcogenides of the IVa metals with layered structures: Preparation and crystal structures of TlCuTIV Q3 (T = Zr, Hf; Q = S, Se) and their relation to the Re3B structure type
Klepp, Kurt O.,Gurtner, Doris
, p. 6 - 11 (1996)
The new compounds TlCuTIVQ3 (T = Zr, Hf; Q = S, Se) were prepared by reacting intimate mixtures of Tl2S or TlSe with stoichiometric amounts of the corresponding Group IV metal, Cu and the corresponding chalcogen at 870°C. The four compounds are isostructural and crystallize in Cmcm, Z = 4 with a = 3.726(4) A, b = 13.987(9) A, c = 9.783(4) A for TlCuZrS3; a = 3.847(1) A, b = 14.381(6) A, c = 10.150(1) A for TlCuZrSe3; a = 3.694(1) A, b = 14.030(3) A, c = 9.750(3) A for TlCuHfS3; and a = 3.831(1) A, b = 14.409(9) A, c = 10.124(2) A for TlCuHfSe3. Their crystal structures were determined from single crystal diffractometer data (Mo Kα radiation, ambient temperature) and refined to conventional R values of 0.016, 0.040, 0.019 and 0.031 respectively. An outstanding feature of their crystal structures is the formation of infinite anionic layers, 2∞-[CuTIVQ3]- parallel to (010), which are separated by Tl+ cations. These layers are built up by edge sharing TQ6 octahedra and distorted CuQ4 tetrahedra. Average T-Q distances are d(Zr-S) = 2.586(1) A, d(Zr-Se) = 2.707(1) A, d(Hf-S) = 2.569(2) A and d(Hf-Se) = 2.694(1) A. Cu-chalcogen distances are d(Cu-S) = 2.318(2) A and d(Cu-Se) = 2.432(3) A respectively. The thallium ions are in bicapped trigonal prismatic chalcogen coordinations. The atomic arrangement corresponds to that of KCuZrS3; based on the thallium-chalcogen partial structure it can be regarded as a filled variant of an anti-Re3B structure type.

Two new sulphosalts Tl3Ag3Sb2S6, (1) and Tl3Ag3As2S6, (2) were prepared in reaction of synthetic binary sulfides: argentite (Ag2S), carlinite (Tl2S) and orpiment (As2S3) or stibnite (Sb2S3), and their crystal structures have been determined using single-crystal data. The compounds are isostructural and crystallize in the space group P21/c (Z = 4), with a = 11.6854(17) ?, b = 11.8602(17) ?, c = 12.1294(18) ?, β = 123.356(2)°, V = 1404.1(4) ?3 for 1, and a = 11.4415(14) ?, b = 11.7530(15) ?, c = 11.9880(16) ?, β = 123.516(3)°, V = 1344.0(3) ?3 for 2. Refinements involving anisotropic displacement parameters for all atoms converged to the conventional R-factors: R1 = 0.0496 for 1 and R1 = 0.0372 for 2. The structures consist of two kinds of slabs alternately situated along [1 0 0] direction and sharing S atoms located between them. The first slab is built up of Tl1S8, Tl2S6, Tl3S5Ag3 coordination polyhedra and Ag3S3Tl3 distorted trigonal pyramid (the average 〈Ag3-S〉 distance is 2.542 for 1 and 2.539 ? for 2) combined with trigonal Sb1S3 or As1S3 coordination pyramids (〈Sb1-S〉 and 〈As1-S〉 are 2.438 and 2.259 ?, respectively). The thallium atom Tl1 is surrounded by eight S atoms forming a square anti-prism (〈Tl1-S〉: 3.393 for 1 and 3.356 ? for 2), while the coordination polyhedron of Tl2 can be described as a significantly distorted trigonal prism or as an extremely distorted octahedron (〈Tl2-S〉: 3.236 ? for 1 and 3.238 ? for 2). Thallium Tl3 is surrounded by six atoms (one Ag, four S at shorter and one S at longer distance), which form a distorted trigonal prism (〈Tl3-S〉: 3.165 ? in 1 and 3.155 ? in 2). The second slab consists of trigonal Sb2S3 or As2S3 coordination pyramids combined with Ag1S4 and Ag2S4 coordination tetrahedra (〈Sb2-S〉 and 〈As2-S〉 are 2.433 and 2.251 ?, respectively; 〈Ag1-S〉: 2.623 ? for 1 and 2.612 ? for 2; 〈Ag2-S〉: 2.623 ? for 1 and 2.630 ? for 2). The most interesting feature of both structures is the existence of short Tl3-Ag3 contacts of 2.959(2) ? in 1 and 2.922(1) ? in 2. These contacts are the shortest found so far and indicate very strong Tl-Ag interactions. They are discussed in terms of metallophilicity principle and relativistic effects. It is also pointed out that if only valence shell electrons are considered (Tl-Ag)2+ group is isoelectronic with the (Hg-Hg)2+ ion, therefore new examples of short Tl-Ag contacts could be expected.

Phase diagram of the Tl-TlI-S system and thermodynamic properties of the compound Tl6SI4
Babanly,Guseinov,Babanly,Sadygov
, p. 90 - 99 (2012/05/07)
Phase equilibria in the Tl-TlI-S composition region of the Tl-S-I system were studied by dif- ferential thermal analysis, x-ray powder diffraction, and measurements of the microhardness and the emf of concentration circuits relative to a thallium electrode. A series of polythermal sections, an isothermal section at 300 K, and a projection of the liquidus surface were constructed. Primary crystallization regions of six phases, including the ternary compounds Tl6SI4 and Tl3SI, were outlined, and the types and coordinates of non- and monovariant equilibria were determined. It was shown that the ternary compound Tl6SI4 forms tie lines with Tl, TlI, Tl2S, Tl4S3, and TlS in the subsolidus region and that the homogeneity region of Tl6SI4 below 400 K does not exceed 1 mol %. From the emf measurement data, the standard thermodynamic functions of formation and standard entropy of the compound Tl6SI4 were calculated: ΔG0 f,298;= -601.7 ± 2.5 kJ/mol, ΔH0 f,298;= -595.1 ± 4.0 kJ/mol, and S0298 = 672 ± 10 J/(mol K).
