|Section2= |Section3= }} Tetrakis(acetonitrile)copper(I) hexafluorophosphate is a coordination compound with the formula ()PF6. It is a colourless solid that is used in the synthesis of copper complexes.〔Silvana F. Rach, Fritz E. Kühn "Nitrile Ligated Transition Metal Complexes with Weakly Coordinating Counteranions and Their Catalytic Applications" Chem. Rev., 2009, volume 109, pp 2061–2080. 〕 ==Structure== As confirmed by X-ray crystallographic studies, copper(I) ion is coordinated to four almost linear acetonitrile ligands in a nearly ideal tetrahedral geometry.〔J. R. Black, W. Levason and M. Webster "Tetrakis(acetonitrile-N)copper(I) Hexafluorophosphate(V) Acetonitrile Solvate"Acta Cryst. (1995). C51, pp. 623-625. 〕 Related complexes are known with other anions including the perchlorate, tetrafluoroborate, and nitrate. With the weakly coordinating anion B(C6F5)4−, salts of ()+ are obtained.〔 The acetonitrile ligands protect the Cu+ ion from oxidation to Cu2+. However, acetonitrile is not bound very strongly to the copper ion, thus the complex is a useful source of Cu(I). 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「Tetrakis(acetonitrile)copper(I) hexafluorophosphate」の詳細全文を読む スポンサード リンク
