英文摘要	The quantum dots (QDs) and metal nanoclusters (MNCs) have recently attracted increasing interest due to their intriguing physical-chemical properties. Nevertheless, the inherent correlations between them have rarely been explored. In this study, we successfully achieved the conversion of the silver QDs ([Ag62S13(SBut)(32)](4+)) to silver MNCs ([Ag62S12(SBut)(32)](2+)) via the electrochemical reduction method. A key intermediate could be obtained by setting the voltage at (-0.6) V, and its atomic structure has been determined to be [Ag62Si3(SBut)(32)](2+) by single crystal X-ray crystallography. After that, the centroid S atom in the Ag14S cubic core can be extruded out of the clusters through the window via an energy favorable route during the reducing process which will be reported for the first time. The detailed conversion process and the accompanying changes of optical properties were studied. Our work revealed a unique case that QDs could be converted to MNCs.
