Abstract
Ionic liquids (IL) are valuable in a variety of applications due to their high electrochemical stability and physical properties. Using the cation 1-methyl-3-octylimidazolium, [OMIM]+, the bromidostannate RTIL [OMIM][Sn+IIBr3], "undercooled melt" [OMIM][Sn+IVBr5], and IL [OMIM]2[Sn+IVBr6] were synthesized. The uncommon solid state structure of [SnBr5]- was elucidated in the form of its RTIL salt. Additionally, the IL based on tribromine-monoanion [OMIM][Br3] was used to dissolve metallic Sn, selectively resulting in the formation of [SnBr3]- as confirmed by Raman spectroscopy. Subsequent cyclic voltammograms (CV) of [SnBr3]- confirmed the deposition potential of metallic Sn and renewal of the polybromide [Br3]-. The RTIL bromidostannates were stable compounds, making a selective electrochemical investigation of the deposition of metallic Sn(0) to Sn(+II)/Sn(+IV) redox process possible, via conductance and CV measurements. The CVs of the RTILs and of solutions in propylene carbonate had the redox couples of Sn(0)/[Sn+IIBr3]-/[Sn+IVBr5]-.
