A new strategy to synthesize a diverse array of organic‐soluble, atomically precise silver clusters has been developed. The technique is based on the miscibility principle of solvents and uses no phase‐transfer agents; various clusters of masses 8.0, 13.4, 22.8, 29.2, and 34.4 kDa were synthesized by changing the reactant composition. We have also synthesized the well‐known Au 25 (SR) 18 cluster by the same method. Among the silver clusters formed, we have studied the new 13.4 kDa species, which has unique steplike features in its UV/Vis spectrum, in detail by mass spectrometry and other analytical techniques. The compound has been assigned as Ag 68 (SR) 34 , which is reported for the first time. By time‐dependent studies, we have shown that the synthetic route follows the bottom‐up approach. The material forms microcrystals. We hope that the proposed synthetic strategy will extend the area of atomically precise clusters.
