The tetranuclear silver(I) 3,5‐bis(trifluoromethyl)pyrazolate adducts with 2,2′‐bipyridine derivatives were prepared by the reaction of trinuclear metal complex with the diimines. It was shown that the product structure depends on the reagents ratio: mono‐ and bisdiimine complexes were synthesized. Compounds obtained possess green phosphorescence in the solid state. The short intramolecular Ag ··· Ag distances (≤ 3 Å) make possible electronic communication between the metal atoms which leads to the dual emissive behavior mainly due to the 3 LC phosphorescence with the impact of 3 MLCT. The behavior observed was rationalized by the TD‐DFT study.
