The reaction of AgNO 3 and sulfobenzoate with neutral ligands led to the formation of three complexes, {[Ag 2 (4‐sb)(Ph 3 P) 2 (3‐apy)] · (H 2 O)} n ( 1 ), {[Ag(PPh 3 )(2‐apy)] · [Ag(PPh 3 )(3‐sb)] · (H 2 O)} n ( 2 ) and [Ag(PPh 3 )(Hdpa)(4‐Hsb)] ( 3 ) (4‐H 2 sb = 4‐sulfobenzoic acid, PPh 3 = triphenylphosphine, 3‐apy = 3‐aminopyridine, 2‐apy = 2‐aminopyridine, 3‐H 2 sb = 3‐sulfobenzoic acid, Hdpa = 2,2′‐dipyridylamine) Complex 1 is a 2D sandwich‐like polymer. Complex 2 is a cation‐anion species and has a 1D polymer structure. Complex 3 is a monomer. Complexes 1 – 3 contain the Ag‐PPh 3 unit and such unit largely hinders the Ag–Ag, π ··· π, Ag ··· π, and Ag ··· C interactions. The experimental results indicated that these three complexes have weaker conductivities than those corresponding silver complexes having abundant weak interactions, especially π ··· π and Ag–Ag interactions, illustrating that the cation‐anion species having potential ability of charge transfer can largely promote the conductivity property.
