Abstract Eight silver (I) complexes with P-donor ligands [triphenylphosphine (PPh3), bis(diphenylphosphino)methane (dppm), 1,2-bis(diphenylphosphino)ethane (dppe) and 1,4-bis(diphenylphosphino)butane(dppb)] and mercaptan ligands [3-amino-5-mercapto-1,2,4-triazole (H2AMTA), 2-amino-5-mercapto-1,3,4-thiadiazole (HAMTD), 2-mercapto-6-nitrobenzothiazole (HMNBT) and 2-mercapto-5-methyl-benzimidazole (HMMBD)] named by [Ag2(PPh3)4(HAMTA)2]n (1), [Ag3(dppm)3(AMTD)2]2(BF4)2·(dppm) (2), [Ag3(dppm)3(AMTD)2]2(ClO4)2·(dppm) (3), [Ag4(dppm)4(MNBT)2](SO4)·(H2O) (4), [Ag4(dppe)4(HAMTA)2(AMTA)] (5), [Ag2(dppb)2(HAMTD)2](CF3SO3)2·2(CH3OH) (6), [Ag2(dppb)2(HMNBT)2](CF3SO3)2 (7) and {[Ag(dppb)(HMMBD)2](CF3SO3)·2(CH3OH)·(H2O)}n (8) are characterized by X-ray diffraction, NMR and fluorescence spectroscopy. Complexes 1 and 8 show 2D network structure. Complexes 2–5 are multi-nuclear clusters. Complexes 6–7 are of di-nuclear structure. In complex 7, the offset π⋯π interactions between the neighboring benzene rings help to form the 1-D infinite chain. All the emission peaks of these complexes are attributed to ligands-centered [π–π∗] transitions.
