摘要

The reaction of AgNO_3 and sulfobenzoate with neutral ligands led to the formation of three complexes, {[Ag_2(4-sb)(Ph _3P)_2(3-apy)]·(H_2O)}_n (1), {[Ag(PPh3)(2-apy)]·[Ag(PPh3)(3-sb)]·(H _2O)}_n (2) and [Ag(PPh3)(Hdpa)(4-Hsb)] (3) (4-H_2sb = 4-sulfobenzoic acid, PPh3 = triphenylphosphine, 3-apy = 3-aminopyridine, 2-apy = 2-aminopyridine, 3-H2sb = 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.
