Abstract: High Resolution Image Download MS PowerPoint Slide The stereochemical-at-metal complexes Δ- and Λ-[Ir(ppy) 2 ( S,R L )]BF 4, where S,R L is a bpy ligand substituted at the 6-position with a chiral diamine or derivative thereof, have been prepared and fully characterized by a combination of empirical and theoretical methods. The differing solubility of the Δ and Λ parent diastereomers in acetone allowed their ready separation. Further functionalization of an external amino group occurred with complete retention of absolute configuration and gave systems capable of binding to a second metal. The facility to coordinate other metals was explored by using in situ 1 H NMR experiments with ZnI 2 . Coordination shifts were seen in the 1 H NMR spectra, confirming the coordination of Zn(II) and showcasing the potential of the complexes as flexible platforms for the construction of asymmetric bimetallics.
