General Description

Bismuth(III) iodide is a chemical compound with the formula BiI3. It is a yellow solid with a high melting point and is insoluble in water. Bismuth(III) iodide is composed of bismuth, a heavy metal, and iodine, a halogen. It is primarily used in organic synthesis and as a precursor for other bismuth compounds. Bismuth(III) iodide has also been investigated for its use in photoconductors and other electronic applications. However, it is important to handle this chemical with care, as bismuth compounds can be toxic if ingested or inhaled.

Solvothermal synthesis and crystal structure determination of AgBiI 4 and Ag3BiI6

AgBiI4 and Ag3BiI6 were synthesized by solvothermal reaction from AgI and BiI3 in diluted HI-solution (20%) at a temperature of 160°C. The greyish-black crystals grow as octahedra (AgBiI4) or hexagonal/trigonal platelets (Ag3BiI 6). AgBiI4 crystallizes in space group Fd3m with a = 1222.3(1) pm (300 K) and Z = 8 whereas Ag3BiI6 shows the space group R3m with a = 435.37(6) pm, c = 2081.0(4) pm (300 K) and Z = 1. Both crystal structures show stacking sequence abcabc... of hexagonal layers containing Iodine. Bismuth and silver are sharing octahedral sites with different mass ratio in both structures. The part of silver which could be localized varies with temperature. This behaviour indicates mobility of silver within the crystal structure. The ionic conductivity of AgBiI4 is explored. AgBiI4 and Ag3BiI6 show close structural relationship, with AgBiI4 as a variant with a higher degree of order.

Preparation and vibrational properties of BiI3 nanocrystals

Nanocrystalline BiI3 with average size of 10-20 nm is prepared by a hydrothermal method at 180-200 °C for the first time. The vibrational properties of as-prepared BiI3 were investigated by the Raman spectra at room temperature.

The synthesis and structural characterization of a novel Bi-Mo double cubane cluster coupled by two bridging oxygen atoms { [Mo3 (BiI3)OS3 (μ-OAc)2 (py)3]2 (μ-O)2}·2 (H2O)

With [Mo3 (μ3-O) (μ-S)3 (μ-OAc)2 (dtp)2 (py)] (dtp=S2P(OC2H5)2)-; OAc=OOCCH -3; py=C5H5N) as the starting material, the reaction together with BiI3 in presence of (H2O) results in a novel Bi-Mo double-cubane cluster coupled by two bridging oxygen atoms { [Mo3 (BiI3) (μ3-O) (μ3-S)3 (μ-OAc)2 (py)3]2 (μ-O)2}·2 (H2O) 2. The cluster 2 has been characterized by IR, Raman, UV-Vis, NMR and single-crystal X-ray study. A comparison is made between these results and those of the previously reported single cubane Bi-Mo cluster [Mo3 (BiI3) (μ3-S)4 (μ-OAc) (dtp)3 (py)] 1.

Phase equilibriums and thermodynamic properties of the system Bi-Te-I

The phase equilibria in the Bi-S-I ternary system and thermodynamic properties of the BiSI and Bi19S27I3 ternary compounds

Phase equilibria in the entire Bi-S-I ternary system were determined experimentally by means of differential thermal analysis (DTA), X-ray diffraction (XRD) techniques and EMF measurements. Several vertical sections, an isothermal section at 300 K, and a liquidus surface projection of the system were constructed and two ternary compounds BiSI and Bi19S 27I3 reported earlier were confirmed. The primary crystallization fields of all phases, the types and coordinates of invariant and monovariant equilibria were determined. Thermodynamic properties of the both BiSI and Bi19S27I3 ternary compounds were studied by electromotive force measurements (EMF) with the bismuth electrode. From the EMF measurements, the partial molar functions of bismuth in alloys and the standard integral thermodynamic functions of BiSI and Bi19S 27I3 were calculated.
