1. A related bidentate ligand with a greater bite angle is spanphos. 2. These catalysts feature mono-anionic bidentate ligands related to salen ligands. 3. In such compounds, the heterocycle is a bidentate ligand . 4. This bidentate ligand chelates metals via the two phosphine groups. 5. Diars is a bidentate ligand used in coordination chemistry. 6. Deprotonation of HNacNac compounds affords anionic bidentate ligands that form a variety of coordination complexes. 7. It is used as a bidentate ligand and is noteworthy for having a particularly wide bite angle. 8. If the carbene is part of a bidentate ligand with a forced geometry, the MIC complex may form preferentially as well. 9. Having three bidentate ligands of only one type gives a propeller-type structure, with two different enantiomers denoted ? and ?. 10. The aldehyde functional group is subject to nucleophilic attack, specifically by amines to form Schiff bases, which serve as bidentate ligands .
