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 Å, which is shorter than the typical metallic silver–silver bond length of 2.889 Å, suggesting an argentophilic interaction.
