Coordination of noble metals by an ambiphilic PBiP pincer ligand: Metallophilic Bi-Cu and Bi-Ag interactions

Employing the PBiP pincer ligand for the coordination of Cu+ and Ag+ leads to heterometallic complexes featuring predominantly Bi → Cu(Ag) interactions. While these complexes dimerize via the chloride ligands, reaction with chloride free metal precursors leads to monomeric complexes in solution, which crystallize in chain-like structures aggregated via the bismuth-bound chloride.
