Abstract

In order to explore if and how salts comprising polycations and salts comprising polyanions might interact, the [AlBr4]⁻ salt of the [Pt@Bi10]⁴⁺ cluster cation was added to the reaction mixture for the synthesis of the supersphere cluster anion [Ge24Sn36Se132]²⁴⁻ from Cs4[Ge4Se10]⋅H2O and SnCl4⋅5 H2O under ionothermal conditions at 120 °C. Indeed, the reaction yields two new compounds, depending on the cation of the used ionic liquid. Apparently, the polycation is not retained under the given conditions, but it acts as a reductant affording Sn^II. In a (C4C1C1im)⁺-based ionic liquid mixture, a unique supertetrahedral anion is obtained that embeds a Cs⁺ cation, 0D-{[Cs@Sn^II 4(Ge^IV 4Se10)4]⁷⁻}, while (C4C1im)⁺ cations stabilize an unprecedented ternary layered anion, 2D-{[Sn^II(Ge^IV 4Se10)]²⁻}. Test reactions with common sources of Sn^II did not afford the new compounds, indicating the necessity of an in situ reduction, for which the polycation seems appropriate.
