Crown ether complexes of tin(II) trifluoromethanesulfonate

The treatment of tin(II) trifluoromethanesulfonate with three differently-sized crown ethers [12]crown-4, [15]crown-5 and [18]crown-6 results in the formation of tin complexes that exhibit dramatically different structural features. The compounds are investigated using experimental techniques and density functional theory calculations.

Graphical abstractThe treatment of tin(II) trifluoromethanesulfonate with crown ethers of different sizes produces salts of three different cationic tin crown ether complexes in excellent yield. The structural features of the cations are evaluated by single-crystal X-ray diffraction and density functional theory calculations.Figure optionsDownload full-size imageDownload as PowerPoint slide
