A Dibismuthane with Olefin Functional Groups: Towards Tridentate Hybrid Chalcogen/Olefin Ligands

The Front Cover shows the evolution of a dibismuthane with olefin functional groups to give a set of potential hybrid ligands featuring chalcogen and olefin coordination sites. In the picture, a dibismuthane caterpillar is moving along a branch towards a delicious meal of chalcogen leaves. The facile insertion of elemental chalcogens into the Bi−Bi bond transforms the caterpillars into colorful butterflies, with a central Bi−E−Bi motif, fluttering around a mountain meadow. DFT calculations were used to investigate the potential of these bismuth compounds to act as tridentate chalcogen/olefin ligands towards a variety of transition metals. These metal atoms are represented by blue flowers in the picture, attracting the butterflies to form a range of coordination entities. More information can be found in the Research Article by C. Lichtenberg and co-workers.
