General Description

Dithallium trisulphide is a chemical compound with the formula Tl2S3. It is a bright yellow, odorless solid that is insoluble in water. Dithallium trisulphide is primarily used in the production of infrared-transmitting materials and as a semiconductor material. It has also been investigated for its potential application in solar cells and as a possible agent for detecting and removing toxic metals from wastewater. However, it is important to handle dithallium trisulphide with caution as it is toxic and can cause skin and eye irritation, as well as respiratory and cardiovascular issues if inhaled or ingested.

The phase equilibria in the Tl-S-I system and electrical properties of the Tl6SI4 and TlS compounds

The phase equilibria in the ternary Tl-S-I system were investigated experimentally by means of powder X-ray diffraction (PXRD) and differential thermal analysis (DTA). Five isopleth sections, liquidus surface projection and room temperature isothermal sec

Phase diagram of the Tl-TlI-S system and thermodynamic properties of the compound Tl6SI4

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).

Tl4Re6X12 (X = S, Se): Crystal growth, structure, and properties

Single crystals of two new phases Tl4Re6S12 and Tl4Re6Se12 isostructural with (Rb,K)4Re6Se12 were synthesized by high-temperature reaction of TlX, Re, and X (X = S, Se). The structure of the selenide was solved by single-crystal X-ray investigation (space group C2/c, R = 0.08). The structure consists of Re6Se8 cluster units interconnected three-dimensionally by four Se and two Se2 bridges. Tl4Re6S12 is isostructural with Tl4Re6Se12. The cell parameters of Tl4Re6S12 and Tl4Re6Se12 are a = 16.653 (2) ?, b = 9.574 (3) ?, c = 11.816 (8) ?, β = 90.62 (2)° and a = 17.177 (3) ?, b = 9.846 (2) ?, c = 12.195 (2) ?, β = 90.71 (2)°, respectively. Z = 4 for both compounds. Physical measurements show that these compounds are semiconducting and diamagnetic, which is consistent with 24 electrons per cluster unit filling the valence band. Bond-order calculations of Tl4Re6Se12 and other related compounds indicate a Re-Re bond order of 1 in all of the known Re6X8 cluster compounds.
