Highly regioselective complexation of tungsten with Eu@C₈₂/Eu@C₈₄: interplay between endohedral and exohedral metallic units induced by electron transfer.

ABSTRACT: Interactions between the inner and outer units through a fullerene cage are of fundamental importance for the creation of molecular spintronics and machines, but the mechanism of such through-cage interplay is still unclear. In this work, we have designed and synthesized two prototypical compounds which contain only a single europium atom inside the cage and merely a tungsten atom coordinating outside to clarify the interactions between the endohedral and exohedral metallic units. They are obtained by reacting a tungsten complex W(CO)₄(Ph₂PC₂H₄PPh₂) (1) with the corresponding metallofullerenes in a highly regioselective manner (2a for Eu@C ₂(5)-C₈₂ and 2b for Eu@C ₂(13
