Abstract
A nonsymmetrical hybrid spacer PONNP pincer ligand is synthesized and fully characterized. The dearomatized PONNP* pincer nickel chloride reacts with silver triflate to generate a unique Ni-Ag bimetallic complex (5). Single-crystal analysis shows a silver-silver distance of 2.693 angstrom, which is shorter than the typical metallic silver-silver bond length of 2.889 angstrom, suggesting an argentophilic interaction.
