Actinide-transition metal bonding in heterobimetallic uranium– and thorium–molybdenum paddlewheel complexes

Abstract

We report the preparation of four heterobimetallic uranium– and thorium–molybdenum paddlewheel complexes. The characterisation data suggest the presence of Mo → An σ-interactions in all cases. These complexes represent unprecedented actinide-group 6 metal–metal bonds, where before heterobimetallic uranium–metal bonds were restricted to group 7–11 metals.
