Bismuth(III) oxide powder

Bismuth compounds are compounds containing the element bismuth (Bi). Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements.[1]

Oxides and sulfides

At elevated temperatures, the vapors of the metal combine rapidly with oxygen, forming the yellow trioxide, Bi
2O
3.[2][3] When molten, at temperatures above 710 °C, this oxide corrodes any metal oxide and even platinum.[4] On reaction with a base, it forms two series of oxyanions: BiO−
2, which is polymeric and forms linear chains, and BiO3−
3. The anion in Li
3BiO
3 is a cubic octameric anion, Bi
8O24−
24, whereas the anion in Na
3BiO
3 is tetrameric.[5]

The dark red bismuth(V) oxide, Bi
2O
5, is unstable, liberating O
2 gas upon heating.[6] The compound NaBiO3 is a strong oxidising agent.[7]

Bismuth sulfide, Bi
2S
3, occurs naturally in bismuth ores.[8] It is also produced by the combination of molten bismuth and sulfur.[9]

Bismuth oxychloride (BiOCl) structure (mineral bismoclite). Bismuth atoms are shown as grey, oxygen red, chlorine green.

Bismuth oxychloride (BiOCl, see figure at right) and bismuth oxynitrate (BiONO3) stoichiometrically appear as simple anionic salts of the bismuthyl(III) cation (BiO+) which commonly occurs in aqueous bismuth compounds. However, in the case of BiOCl, the salt crystal forms in a structure of alternating plates of Bi, O, and Cl atoms, with each oxygen coordinating with four bismuth atoms in the adjacent plane. This mineral compound is used as a pigment and cosmetic (see below).[10]

Bismuthine and bismuthides

Unlike the lighter pnictogens nitrogen, phosphorus, and arsenic, but similar to antimony, bismuth does not form a stable hydride. Bismuth hydride, bismuthine (BiH
3), is an endothermic compound that spontaneously decomposes at room temperature. It is stable only below −60 °C.[5] Bismuthides are intermetallic compounds between bismuth and other metals.[11]

In 2014 researchers discovered that sodium bismuthide can exist as a form of matter called a “three-dimensional topological Dirac semi-metal” (3DTDS) that possess 3D Dirac fermions in bulk. It is a natural, three-dimensional counterpart to graphene with similar electron mobility and velocity. Graphene and topological insulators (such as those in 3DTDS) are both crystalline materials that are electrically insulating inside but conducting on the surface, allowing them to function as transistors and other electronic devices. While sodium bismuthide (Na
3Bi) is too unstable to be used in devices without packaging, it can demonstrate potential applications of 3DTDS systems, which offer distinct efficiency and fabrication advantages over planar graphene in semiconductor and spintronics applications.[12][13]

Halides

The halides of bismuth in low oxidation states have been shown to adopt unusual structures. What was originally thought to be bismuth(I) chloride, BiCl, turns out to be a complex compound consisting of Bi5+
9 cations and BiCl2−
5 and Bi
2Cl2−
8 anions.[5][14] The Bi5+
9 cation has a distorted tricapped trigonal prismatic molecular geometry and is also found in Bi
10Hf
3Cl
18, which is prepared by reducing a mixture of hafnium(IV) chloride and bismuth chloride with elemental bismuth, having the structure [Bi+
] [Bi5+
9] [HfCl2−
6]
3.[5]: 50  Other polyatomic bismuth cations are also known, such as Bi2+
8, found in Bi
8(AlCl
4)
2.[14] Bismuth also forms a low-valence bromide with the same structure as "BiCl". There is a true monoiodide, BiI, which contains chains of Bi
4I
4 units. BiI decomposes upon heating to the triiodide, BiI
3, and elemental bismuth. A monobromide of the same structure also exists.[5] In oxidation state +3, bismuth forms trihalides with all of the halogens: BiF
3, BiCl
3, BiBr
3, and BiI
3. All of these except BiF
3 are hydrolyzed by water.[5]

Bismuth(III) chloride reacts with hydrogen chloride in ether solution to produce the acid HBiCl
4.[15]

The oxidation state +5 is less frequently encountered. One such compound is BiF
5, a powerful oxidizing and fluorinating agent. It is also a strong fluoride acceptor, reacting with xenon tetrafluoride to form the XeF+
3 cation:[15]

BiF
5 + XeF
4 → XeF+
3BiF−
6

Aqueous species

In aqueous solution, the Bi3+
 ion is solvated to form the aqua ion Bi(H
2O)3+
8 in strongly acidic conditions.[16] At pH > 0 polynuclear species exist, the most important of which is believed to be the octahedral complex [Bi
6O
4(OH)
4]6+
.[17]
