A thiophosphate (or phosphorothioate, PS ) is a family of compounds and anions with the general chemical formula PS4-xOx3− (x = 0, 1, 2, or 3). The state of protonation is usually not specified. They could be bound to as many as three protons for the neutral H3PS4-xOx species. Two protons correspond to the related monoanions, and one proton for the dianions. The trianions are highly basic and do not exist in appreciable concentrations in solution. Thiophosphates are tetrahedral anions, with the phosphorus at the center of the tetrahedron. ==Monothiophosphate== Monothiophosphates are formally derived from the anion PO3S3−, which has C3v symmetry.. A number of insecticides feature organic monothiophosphate center, including diazinon, parathion, and malathion. They have the formula (RO)2PS(OAr), where R = methyl or ethyl and Ar = an aryl or related group. Coordination complexes by oxygen and sulphur are known. In the laboratory monothiophosphate is used as an analogue of phosphate in biochemistry. Monothiophosphate esters are biochemical reagents used in the study transcription, substitution interference assays. 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「Thiophosphate」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
