摘要

Trinuclear silver(I) thiolate and silver(I) thiocarboxylate complexes [Ag_3(μ-dppm)_3(μn-SR)_2] (ClO_4) [n = 2, R = C_6H_4Cl-4 (1) and C{O}Ph (2); n = 3, R = tBu (3)], pentanuclear silver(I) thiolate complex [Ag _5(μ-dppm)_4(μ_3-SC_6H _4NO_2-4)_4](PF_6) (4), and hexanuclear silver(I) thiolate complexes [Ag_6(μ-dppm) _4(μ_3-SR)_4]Y_2 [Y = ClO _4, R =C_6H_4CH_3-4 (5) and C _(10)H_7 (2-naphthyl) (7); Y = PF_6, R = C _6H_4OCH_3-4(6)], were synthesized [dppm = bis(diphenylphosphanyl)methane] and their crystal structures as well as photophysical properties were studied. In the solid state at 77 K, trinuclear silver(I) thiolate and silver(I) thiocarboxylate complexes 1 and 2 exhibit luminescence at 470-523 nm, tentatively attributed to originate from the ~3IL (intraligand) of thiolate or thiocarboxylate ligands, whereas hexanuclaer silver(I) thiolate complexes 5 and 7 produce dual emission, in which high-energy emission is tentatively attributed to come from the ~3IL of thiolate ligands and low-energy emission is tentatively assigned to come from the admixture of metal?metal bond-to-ligand charge-transfer (MMLCT) and metal-centered (MC) excited states.
