Methyl viologen iodobismuthates

Abstract

The interaction of iodobismuthate anions and methyl viologen [MV]2+ cations in aqueous solutions led to the formation of three compounds, two of which were identified as [MV][BiI5] and [MV]3[Bi2I11]I. Hybrid iodobismuthates [MV]3[Bi2I11]I and [MV]3[Bi2I9]2(DMF)3(H2O) were isolated from dimethylformamide (DMF). The heating of the latter material (up to 200 oC) resulted in a mixture of products, one of which was identified as [MV][BiI5]. A simple antisolvent precipitation method was proposed to create the [MV][BiI5]/SiO2 composite material.
