Cyclic alkyl(amino) carbene‐anchored monoanionic phosphorus species have been introduced as the rising ligand to stabilize three unprecedented homo (Ag I )‐ and mixed (Ag 0 /Ag I )‐valence silver nanoclusters Ag 29 , Ag 12 and Ag 8 in the solid state with defined structures. The neutral Ag 29 and Ag 8 clusters showed electron paramagnetic resonance at room temperature, whereas the green‐emitting tri‐cationic Ag 12 cluster is diamagnetic and NMR active.
