Phosphorus sulfides comprise a family of inorganic compounds containing only phosphorus and sulfur.These compounds have the formula P 4 S n with n ≤ 10. Two are of commercial significance, phosphorus pentasulfide (P 4 S 10), which is made on a kiloton scale for the production of other organosulfur compounds, and phosphorus sesquisulfide (P 4 S 3), used in the production of "strike anywhere ...
Phosphorus pentasulfide is the inorganic compound with the formula P 2 S 5 or P 4 S 10 . This yellow solid is the one of two phosphorus sulfides of commercial value. Samples often appear greenish-gray due to impurities. It is soluble in carbon disulfide but reacts with many other solvents such as alcohols, DMSO, and DMF. [3]
Ammonium pentasulfide is a chemical compound with the chemical formula (NH 4) 2 S 5. [1] Synthesis.
A solid salt of the diiodine cation may be obtained by oxidising iodine with antimony pentafluoride: [11] 2 I 2 + 5 SbF 5 2 I 2 Sb 2 F 11 + SbF 3. The salt I 2 Sb 2 F 11 is dark blue, and the blue tantalum analogue I 2 Ta 2 F 11 is also known. Whereas the I–I bond length in I 2 is 267 pm, that in I +

The interhalogen bond in diiodine is the weakest of all the halogens. As such, 1% of a sample of gaseous iodine at atmospheric pressure is dissociated into iodine atoms at 575 °C. Temperatures greater than 750 °C are required for fluorine, chlorine, and bromine to dissociate to a similar extent.
Dithiophosphate has the formula [PO 2 S 2] 3−, which has C 2v symmetry. Sodium dithiophosphate, which is colorless, is the major product from the reaction of phosphorus pentasulfide with NaOH: [6] P 2 S 5 + 6 NaOH → 2 Na 3 PO 2 S 2 + H 2 S + 2 H 2 O. Dithiophosphoric acid is obtained by treatment of barium dithiophosphate with sulfuric acid:
The compound (C 5 H 5) 2 TiS 5 is an example of a polysulfide complex. Polysulfides are a class of chemical compounds derived from anionic chains of sulfur atoms. [1] There are two main classes of polysulfides: inorganic and organic.
