As versatile ligands with extraordinary coordination capabilities, RPH 2 (R = alkyl or aryl) are rarely used in constructing metal nanoclusters due to their volatility, toxicity, spontaneous flammability, and susceptibility oxidation. In this work, we designed a primary tertiary phosphorus-bound diphosphine chelator (2-Ph PC 6 H 4 PH ) create ultrastable silver metallic aromaticity. By controlling the deprotonation rate of 2-Ph adjusting templates, successfully synthesized two near-infrared emissive nanoclusters, Ag30 Ag32 , which have analogous icosidodecahedral Ag 30 shells an I h symmetry. Deprotonated ligand P α C β 2− exhibits mode μ 5 -η 1 (P ),η ,P ), endows unique aromaticity . The solution-processed organic light-emitting diodes based on achieve external quantum efficiency 15.1%, representing breakthrough application near-infrared–emitting devices. This work represents special system for synthesizing ligand-protected coinage opens up horizons creating distinct geometries
