Alkali-metal- and halide-free dinuclear mixed-valent samarium and europium complexes†
We describe the synthesis of mixed-valent (Ln(II)/Ln(III)) dilanthanide complexes supported by a calixpyrrole ligand. The complexes are obtained by one-electron reduction of Ln(III)/Ln(III) complexes and are alkali-metal- and halide-free. The complexes are designed to activate small molecules by taking advantage of both the base and the one-electron reductant contained in their structure. We demonstrate a proof-of-principle concept of this mechanism by activating water and silanol.
