σ-Accepting Properties of a Chlorobismuthine Ligand

BiZness as usual? Not exactly! The bismuth atom of the tridentate diphosphinobismuthine (o‐(Ph2P)C6H4)2BiCl behaves as a Z rather than L ligand when in the coordination sphere of late transition metals such as gold. The σ‐acceptor behavior of Bi is supported by its disphenoid coordination geometry a...

Zusammenfassung:BiZness as usual? Not exactly! The bismuth atom of the tridentate diphosphinobismuthine (o‐(Ph2P)C6H4)2BiCl behaves as a Z rather than L ligand when in the coordination sphere of late transition metals such as gold. The σ‐acceptor behavior of Bi is supported by its disphenoid coordination geometry and theoretical studies, which show a Au→Bi interaction.
