The reaction of the organometallic diarsene complex [Cp 2 Mo 2 (CO) 4 (η 2 ‐As 2 )] ( 1 ) with Ag[Al{OC(CF 3 ) 3 } 4 ] (Ag[TEF]) yielded the Ag I monomer [Ag(η 2 ‐ 1 ) 3 ][TEF] ( 2 ). This compound exhibits dynamic behavior in solution, which allows directed selective synthesis of unprecedented organometallic–organic hybrid assemblies upon its reaction with N‐donor organic molecules by a stepwise pathway, which is supported by DFT calculations. Accordingly, the reaction of 2 with 2,2′‐bipyrimidine ( L1 ) yielded the dicationic molecular compound [{(η 2 ‐ 1 ) 2 Ag} 2 (μ‐ L1 )][TEF] 2 ( 3 ) or the 1D polymer [{(η 2 ‐ 1 )Ag}(μ‐ L1 )] n [TEF] n ( 4 ) depending on the ratio of the reactants. However, its reactions with the pyridine‐based linkers 4,4′‐bipyridine ( L2 ), 1,2‐bis(4‐pyridyl)ethylene ( L3 ) and 1,2‐bis(4‐pyridyl)ethyne ( L4 ) allowed the formation of the 2D polymers [{(η 2 ‐ 1 )Ag} 2 (μ‐ L x ) 3 ] n [TEF] 2 n [ L x =L2 ( 5 ), L3 ( 6 ), L4 ( 7 ), respectively]. Additionally, this concept was extended to step‐by‐step one‐pot reactions of 1 , [Ag(CH 3 CN) 3 ][Al{OC(CF 3 ) 2 (CCl 3 )} 4 ] ([Ag(CH 3 CN) 3 ][TEF Cl ]) and linkers L2 – L4 to produce the 2D polymers [{(η 2 ‐ 1 )Ag} 2 (μ, L x ) 3 ] n [TEF Cl ] 2 n [ Lx = L2 ( 8 ), L3 ( 9 ), L4 ( 10 ), respectively].
