Peroxide solvation by a toroidal lithium inverse crown ether complex assembled by multidentate polyimido sulfonates.

In this communication we present the synthesis of the inverse crown ether complex [Li(2)O(2)·Li(4){CH(2)(N(Me)CH(2)S(NtBu)(2))(2)}(2)] (1) which is able to accommodate peroxide in a torus of lithium ions.
