|Section2= |Section3= |Section8= }} Phosphorus sesquisulfide is the inorganic compound with the formula 43. It was developed by Henri Sevene and Emile David Cahen in 1898 as part of their invention of friction matches that did not pose the health hazards of white phosphorus.() This yellow solid is one of two commercially produced phosphorus sulfides. It is a component of "strike anywhere" matches. Depending on purity, samples can appear yellow-green to grey. The compound was discovered by G. Lemoine and first produced safely in commercial quantities in 1898 by Albright and Wilson. It dissolves in an equal weight of carbon disulfide (CS2). Unlike some other phosphorus sulfides, P4S3 is slow to hydrolyze and has a well-defined melting point. ==Structure and synthesis== The molecule has C3v symmetry. It is a derivative of the tetrahedral (P4) unit from insertion of sulfur into three P-P bonds. The P-S and P-P distances are 2.090 and 2.235 Å, respectively. P4Se3 and P4S3 adopt the same structures.〔 These compounds can be melted together and form mixed crystals of one dissolved in the other.〔Burns, G.R., and Sarfati, J.D., "Raman spectra of tetraphosphorus triselenide doped in tetraphosphorus trisulphide", ''Solid State Communications'' 66(4):347–49, April 1988 | 〕 Under higher temperatures, mixed chalcogenide molecules P4S2Se and P4SSe2 will form.〔Burns, G.R., Rollo, J.R., and Sarfati, J.D.: "Raman spectra of the tetraphosphorus trichalcogenide cage molecules P4S2Se and P4SSe2", ''Inorganica Chimica Acta'' 161(1):35–38, 3 July 1989 | 〕 P4S3 is produced by the reaction of red or white phosphorus with sulfur. Excess sulfur gives phosphorus pentasulfide (P4S10). It is estimated that 150 ton/y were produced in 1989. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「phosphorus sesquisulfide」の詳細全文を読む スポンサード リンク
