Template:Chembox Footer/trackingTemplate:Short description

The Page Module:Chem2/styles.css has no content.S3 molecule, known as trisulfur, sulfur trimer, thiozone, or triatomic sulfur, is a cherry-red allotrope of sulfur. It comprises about 10% of vaporised sulfur at 713 K (440 °C; 824 °F) and 1,333 Pa (10.00 mmHg; 0.1933 psi). It has been observed at cryogenic temperatures as a solid. Under ordinary conditions it converts to cyclooctasulfur.

Structure and bonding

In terms of structure and bonding Page Module:Chem2/styles.css has no content.S3 and ozone (Page Module:Chem2/styles.css has no content.O3) are similar. Both adopt bent structures and are diamagnetic. Although represented with S=S double bonds, the bonding situation is more complex.[1]

The S–S distances are equivalent and are 191.70±0.01 pm, and with an angle at the central atom of 117.36°±0.006°.[2] However, cyclic Page Module:Chem2/styles.css has no content.S3, where the sulfur atoms are arranged in an equilateral triangle with three single bonds (similar to cyclic ozone and cyclopropane), is calculated to be higher in energy than the bent structure experimentally observed.[3] A similar structure has been predicted for ozone, but has not been observed.

The name thiozone was invented by Hugo Erdmann in 1908 who hypothesized that Page Module:Chem2/styles.css has no content.S3 comprises a large proportion of liquid sulfur.[4] However its existence was unproven until the experiments of J. Berkowitz in 1964.[5] Using mass spectrometry, he showed that sulfur vapour contains the Page Module:Chem2/styles.css has no content.S3 molecule. Above 1,200 °C (2,190 °F) Page Module:Chem2/styles.css has no content.S3 is the second most common molecule after Page Module:Chem2/styles.css has no content.S2 in gaseous sulfur.[5] In liquid sulfur the molecule is not common until the temperature is high, such as 500 °C (932 °F). However, small molecules like this contribute to most of the reactivity of liquid sulfur.[5] Page Module:Chem2/styles.css has no content.S3 has an absorption peak of 425 nm (violet) with a tail extending into blue light.[5]

Page Module:Chem2/styles.css has no content.S3 can also be generated by photolysis of Page Module:Chem2/styles.css has no content.S3Cl2 embedded in a glass or matrix of solid noble gas.[5]

Natural occurrence

Page Module:Chem2/styles.css has no content.S3 occurs naturally on Io in volcanic emissions. Page Module:Chem2/styles.css has no content.S3 is also likely to appear in the atmosphere of Venus at heights of 20 to 30 km, where it is in thermal equilibrium with Page Module:Chem2/styles.css has no content.S2 and Page Module:Chem2/styles.css has no content.S4.[6]Template:Rp The reddish colour of Venus' atmosphere at lower levels is likely to be due to Page Module:Chem2/styles.css has no content.S3.[6]Template:Rp

Reactions

Page Module:Chem2/styles.css has no content.S3 reacts with carbon monoxide to make carbonyl sulfide and Page Module:Chem2/styles.css has no content.S2.

Formation of compounds with a defined number of sulfur atoms is possible:

Page Module:Chem2/styles.css has no content.S3 + S2O → S5O (cyclic)[7]

Radical anion

File:Lazurite.jpg
Lazurite contains Page Module:Chem2/styles.css has no content.S−3.

Although Page Module:Chem2/styles.css has no content.S3 is elusive under ordinary conditions, the intensely blue radical anion Page Module:Chem2/styles.css has no content.S−3 is abundant.[8] The anion is sometimes called thiozonide,[9] by analogy with the ozonide anion, Page Module:Chem2/styles.css has no content.O−3, to which it is valence isoelectronic. The preferred IUPAC name is trisulfanidylo. The gemstone lapis lazuli and the mineral lazurite (from which the pigment ultramarine is derived) contain Page Module:Chem2/styles.css has no content.S−3. International Klein Blue, developed by Yves Klein, also contains the Page Module:Chem2/styles.css has no content.S−3 radical anion.[10] The blue colour is due to the C2A2 transition to the X2B1 electronic state in the ion,[9] causing a strong absorption band at 610–620 nm or 2.07 eV (in the orange region of the visible spectrum).[11] The Raman frequency is 523 cm−1 and another infrared absorption is at 580 cm−1.[5]

The Page Module:Chem2/styles.css has no content.S−3 ion has been shown to be stable in aqueous solution under a pressure of 0.5 GPa (73,000 psi), and is expected to occur naturally at depth in the Earth's crust where subduction or high pressure metamorphism occurs.[12] This ion is probably important in movement of copper and gold in hydrothermal fluids.[13]

Lithium hexasulfide (which contains Page Module:Chem2/styles.css has no content.S−6, another polysulfide radical anion) with tetramethylenediamine solvation dissociates acetone and related donor solvents to Page Module:Chem2/styles.css has no content.S−3.[14]

The Page Module:Chem2/styles.css has no content.S−3 radical anion was also made by reducing gaseous sulfur with Page Module:Chem2/styles.css has no content.Zn2+ in a matrix. The material is strongly blue-coloured when dry and changes colour to green and yellow in the presence of trace amounts of water.[15] Another way to make it is with polysulfide dissolved in hexamethylphosphoramide where it gives a blue colour.[16]

Other methods of production of Page Module:Chem2/styles.css has no content.S−3 include reacting sulfur with partially hydroxylated magnesium oxide at 400 °C.[17]

Raman spectroscopy can be used to identify Page Module:Chem2/styles.css has no content.S−3, and it can be used non-destructively in paintings. The bands are 549 cm−1 for symmetric stretch, 585 cm−1 for asymmetric stretch, and 259 cm−1 for bending.[18] Natural materials can also contain Page Module:Chem2/styles.css has no content.S−2 which has an optical absorption at 390 nm and Raman band at 590 cm−1.[18]

Trisulfide ion

The trisulfide ion, Page Module:Chem2/styles.css has no content.S2−3 is part of the polysulfide series. The sulfur chain is bent at an angle of 107.88°.[5] Strontium trisulfide (Page Module:Chem2/styles.css has no content.SrS3) has a S–S bond length of 205 pm.[5] The bonds are single. It is isoelectronic to sulfur dichloride.
