Description
Summary:The synthesis of bis[di‐ n ‐alkyl(fluoro)stannyl]methanes, [(R 2 )FSn] 2 CH 2, ( 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 19 F and 119 Sn NMR spectroscopy, osmometric molecular mass determination and electrospray mass spectrometry (ESMS). 19 F and 119 Sn 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(Ph 2 )Sn] 2 CH 2 , 3 and 4 exhibit a drastically improved lifetime, while retaining their high preference for fluoride over all other lipophilic anions evaluated.
