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 ...
Its tetrahedral molecular structure is similar to that of adamantane and almost identical to the structure of phosphorus pentoxide. [4] Phosphorus pentasulfide is obtained by the reaction of liquid white phosphorus (P 4) with sulfur above 300 °C. The first synthesis of P 4 S 10 by Berzelius in 1843 [5] was by this method.
P 4 Se 3 and P 4 S 3 adopt the same structures. [1] These compounds can be melted together and form mixed crystals of one dissolved in the other. [4] Under higher temperatures, mixed chalcogenide molecules P 4 S 2 Se and P 4 SSe 2 will form. [5] P 4 S 3 is produced by the reaction of red or white phosphorus with sulfur. Excess sulfur gives ...
Diphosphorus trisulfide (sometimes called phosphorus trisulfide) is a phosphorus sulfide with the formula of P 2 S 3. The substance is highly unstable and difficult to study. [3] In contrast, the formal dimer P 4 S 6 is well-known.
Autodecomposition from heat gives phosphorus fluorides, sulfur, and phosphorus: PSF 3 → S + PF 3 → ... Hot PSF 3 reacts with glass, producing SF 4, sulfur and elemental phosphorus. If water is present and the glass is leaded, then the hydrofluoric acid and hydrogen sulfide combination produces a black plumbous sulfide deposit on the inner ...
A portion of the structure of Cu 3 P, highlighting the highly crosslinked nature common to many transition metal phosphides (Cu = orange, P = purple). In chemistry, a phosphide is a compound containing the P 3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [1]
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 ]
General structure of a sulfide with the blue marked functional group. In organic chemistry, a sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. [1]
