General Description

Bismuth(III) bromide, also known as bismuth tribromide, is an inorganic compound with the formula BiBr3. It is a heavy, crystalline solid that appears as a dark reddish-brown color, but in its pure form, it is colorless. This substance has a molecular weight of 558.52 g/mol and a melting point of 218 °C. It is a strong Lewis acid and it is regarded as being corrosive. Bismuth(III) bromide can conduct electricity due to the presence of mobile ions and it is highly soluble in water, alcohol, and acetone. It's often used as a reagent in organic synthesis. However, it is extremely sensitive and may react violently when it comes into contact with other chemicals, thus proper handling and storage is needed.

Synthesis and structures of novel ring compounds of bismuth with tris(trimethylsilyl)silyl and -stannyl substituents - [(Me3Si)3Si]4Bi4 and [(Me3Si)3Sn]6Bi8

A bicyclo[3.3.0]octane-like core consisting of eight bismuth atoms is found in the novel octabismuthane Bi8[Sn(SiMe3)3]6. It is prepared like Bi4[Si(SiMe3)3]4 by reduction of BiBr3 with Li(thf)3E(SiMe3)3 (E = Si, Sn) together with (Me3Si)6E2. Both bismuth ring compounds have been characterized by single crystal X-ray crystallography.

Homologous silver bismuth chalcogenide halides (N, x)P. I. syntheses and crystal structures of the (0, 1)P compound AgBi 2S2Cl3 and of three members of the (1, x)P solid solution series Ag2xBi4-2xS 6-4xBr4x

AgBi2S2Cl3 and three members of the Ag2xBi4-2xS6-4xBr4x solid solution (x = 0.50 (I), x = 0.64 (II), and x = 0.73 (III)) were synthesized from Bi 2S3, AgX and BiSX (X = Cl, Br) at 720 K. X-ray diffraction on single crystals revealed that the compounds crystallize in the monoclinic space groups C2/m (No. 12) with a = 1257.3(3), b = 400.0(1), c = 804.1(2) pm, β = 111.0(1)° for AgBi2S2Cl3, a = 1331.3(5), b = 408.0(2), c = 972.0(3) pm, β = 90.8(1)° for (I), a = 1328.9(4), b = 408.5(1), c = 973.4(4) pm, β = 90.9(1)° for (II), and a = 1332.4(3), b = 409.3(1), c = 974.3(2) pm, β = 90.4(1)° for (III). AgBi2S2Cl3 adopts a variant of the InBi 2S4Cl structure type, the isostructural compounds (I), (II) and (III) are related to the orthorhombic FeUS3 type. All four compounds belong to homologous series with general formula [BiSA] 2·[AgxBi1-xS2-2xX 2x-1]N+1 (X = Cl, Br), which resemble minerals of the pavonite series. They are characterized by the parameters N and x and are denoted (N, x)P. In the crystal structures, two kinds of layered modules, A and B, alternate. Modules of type B are composed of chains of edge-sharing [MBr4Z2] octahedra (M = Ag/Bi; X = Cl, Br; Z = S/X) and vary in thickness N. Modules of type A uniformly consist of rows of paired monocapped trigonal prisms around Bi atoms with [MS4Z 2] octahedra around mixed-occupied metal positions (M = Ag/Bi) between them. Ag-Bi2S2Cl3 comprises modules of type A only (N = 0) and is the silver-rich end-member (x = 1) in the series (0, x)P. (I) to (III) belong to the (1, x)P series with B modules of thickness N = 1. Calculations of the electronic band structures indicate that the compounds should act as indirect semiconductors with band gaps between 1.5 and 0.6 eV.

Trapping molecular bromine: A one-dimensional bromobismuthate complex with Br2 as a linker

The reaction between solid (NMP)n{[BiBr4]}n (1) (NMP = N-methylpyridinium) and Br2, generated in situ in HBr solution, results in the formation of (NMP)3[Bi2Br9]·Br2 (2). In the structure of 2, dibromine molecules connect discrete binuclear [Bi2Br9]3- anions into an extended network. Complex 2 is thermally stable (up to 150 °C).
