Abstract
AbstractThe hypercoordinate [SiH6]2− anion is not stable in solution. Here, we report the room temperature, solution stable molecular [SiH6]2− complex, [{KCa(NON)(OEt2)}2][SiH6] (NON=4,5‐bis(2,6‐diisopropylanilido)‐2,7‐di‐tert‐butyl‐9,9‐dimethyl‐xanthene)), where the [SiH6]2− anion is stabilised within a supramolecular assembly that mimics the solid‐state environment of the anion in the lattice of K2SiH6. Solution‐state reactivity of the complex towards carbon monoxide, benzaldehyde, azobenzene and acetonitrile is reported, yielding a range of reduction and C−C coupled products.
