• In order to understand the structure–property correlation and explore the application of metal nanoclusters, it is important and intriguing to determine their crystal structure and obtain high-yield. At the same time, this is also a challenge in nanoscience and technology. Here, we report the highly efficient synthesis of Pt 1 Ag 28 nanocluster via one-pot chemical wet method. The crystal structure of Pt 1 Ag 28 nanocluster was determined by X-ray crystallography to be a face centered cubic (FCC) kernel. This novel structure is the structural isomerization of Pt 1 Ag 28 nanocluster reported before. This phenomenon is first discovered in the synthesis of alloy nanoclusters. In addition, Pt 1 Ag 28 nanocluster has high yield and exhibits potential optics in the near infrared (NIR) fluorescent imaging. The time-dependent density functional theory (TD-DFT) calculation implied that the optical property of Pt 1 Ag 28 was sensitive to its structure. This work provides a simple method to synthesize alloy nanoclusters with structural isomerization.
