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.
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 pentabromide – PBr 5; Phosphorus pentafluoride – PF 5; Phosphorus pentasulfide – P 4 S 10; Phosphorus pentoxide – P 2 O 5; Phosphorus sesquisulfide – P 4 S 3; Phosphorus tribromide – PBr 3; Phosphorus trichloride – PCl 3; Phosphorus trifluoride – PF 3; Phosphorus triiodide – PI 3; Phosphotungstic acid – H 3 PW 12 ...
The formal oxidation state of phosphorus is +4. The oxygen analogue is the hypodiphosphate anion, P 2 O 4− 6. P 3 S 3− 9 contains a six-membered P 3 S 3 ring. The ammonium salt is produced by reaction of P 4 S 10 in liquid ammonia. [13] Another way of visualising the structure is that it is the P 4 S 10 adamantane (P 4 O 10) structure with ...
White phosphorus is widely used to make organophosphorus compounds through intermediate phosphorus chlorides and two phosphorus sulfides, phosphorus pentasulfide and phosphorus sesquisulfide. [118] Organophosphorus compounds have many applications, including in plasticisers , flame retardants , pesticides , extraction agents, nerve agents and ...
Arsenic pentasulfide, As 2 S 5, similar structure to phosphorus pentasulfide (β-P 2 S 5) Tetraarsenic tetrasulfide, As 4 S 4 (2 isomers): the mineral realgar; the mineral pararealgar; Tetraarsenic trisulfide, As 4 S 3, the mineral α- or β- dimorphite
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction . [ 2 ]
