Nd─Nd Bond in I_h and D_5h Cage Isomers of Nd₂ @C₈₀ Stabilized by Electrophilic CF₃ Addition.

ABSTRACT: Synthesis of molecular compounds with metal-metal bonds between 4f elements is recognized as one of the fascinating milestones in lanthanide metallochemistry. The main focus of such studies is on heavy lanthanides due to the interest in their magnetism, while bonding between light lanthanides remains unexplored. In this work, the Nd─Nd bonding in Nd-dimetallofullerenes as a case study of metal-metal bonding between early lanthanides is demonstrated. Combined experimental and computational study proves that pristine Nd₂ @C₈₀ has an open shell structure with a single electron occupying the Nd─Nd bonding orbital. Nd₂ @C₈₀ is stabilized by a one-electron reduction and further by the electrophilic CF₃ addition to [Nd₂ @C_80</
