Abstract Ligand‐protected heterometallic nanoclusters in contrast to homo‐metal counterparts show more broad applications due the synergistic effect of hetero‐metals but their controllable syntheses remain a challenge. Among nanoclusters, monovalent Ag‐Cu compounds are rarely explored much difference Ag(I) and Cu(I) such as atom radius, coordination habits, redox potential. Encouraged by copper‐catalyzed alkyne‐azide cycloaddition (CuAAC) reaction, comproportionation reaction Cu(II)X 2 Cu(0) presence (PhC≡CAg) n complex molybdate generated core‐shell peanut‐shaped 66‐nuclear Ag(I)‐Cu(I) nanocluster, [(Mo 4 O 16 ) @Cu 12 Ag 54 (PhC≡C) 50 ] (referred Cu ). The structure composition nanocluster fully characterized. X‐ray single crystal diffraction reveals that has silver(I)/copper(I) nanocage protected fifty phenylacetylene ligands µ 3 –modes encapsulated two mutually twisted tetramolybdates. Heterometallic contains 54‐Ag‐atom outer ellipsoid silver cage decorated copper inside wall. Nanosized is ‐type narrow‐band‐gap semiconductor with good photocurrent response. Preliminary experiments demonstrates itself activated carbon supported /C effective catalysts for 1,3‐dipole between alkynes azides at ambient conditions. work provides not only new synthetic route toward also an important intermediate CuAAC catalytic reaction.
