	abstract = {Abstract Ligand-induced surface restructuring with heteroatomic doping is used to precisely modify the surface of a prototypical [Au$_{2}$$_{5}$(SR{\textonesuperior})$_{1}$$_{8}$]$^{-}$ cluster (1) while maintaining its icosahedral Au$_{1}$$_{3}$ core for the synthesis of a new bimetallic [Au$_{1}$$_{9}$Cd$_{3}$(SR{\texttwosuperior})$_{1}$$_{8}$]$^{-}$ cluster (2). Single-crystal X-ray diffraction studies reveal that six bidentate Au$_{2}$(SR{\textonesuperior})$_{3}$ motifs (L2) attached to the Au$_{1}$$_{3}$ core of 1 were replaced by three quadridentate Au$_{2}$Cd(SR{\texttwosuperior})$_{6}$ motifs (L4) to create a bimetallic cluster 2. Experimental and theoretical results demonstrate a stronger electronic interaction between the surface motifs (Au$_{2}$Cd(SR{\texttwosuperior})$_{6}$) and the Au$_{1}$$_{3}$ core, attributed to a more compact cluster structure and a larger energy gap of 2 compared to that of 1. These factors dramatically enhance the photoluminescence quantum efficiency and lifetime of crystal of the cluster 2. This work provides a new route for the design of a wide range of bimetallic/alloy metal nanoclusters with superior optoelectronic properties and functionality.},
