摘要:Abstractthe Synthesis Of Bis[di‐n‐alkyl(Fluoro)Stannyl]Methanes,[(R2)Fsn]2Ch2,(3,R = N‐octyl; 4,R = N‐dodecyl),Is Reported And Their Unprecedented Dimeric Structure In Solution With Pentacoordinate Tin Atoms Is Rationalized On The Basis Of 19F And 119Sn NMR Spectroscopy,Osmometric Molecular Mass Determination And Electrospray Mass Spectrometry (Esms). 19F And 119Sn Mas NMR And Mössbauer Spectroscopy Also Indicate Pentacoordinate Tin Atoms For The Solid State. The Ability Of Compounds 3 And 4 To Bind Fluoride Ion Selectively And Reversibly Is Evaluated Through Potentiometric Measurements. Compared With The Previously Reported Organotin(Iv)‐based Fluoride Ionophore [cl(Ph2)Sn]2Ch2,3 And 4 Exhibit A Drastically Improved Lifetime,While Retaining Their High Preference For Fluoride Over All Other Lipophilic Anions Evaluated.
