A novel, monomeric triphenylphosphine silver(I) complex [Ag(Htsa)(PPh3)3] (H2tsa=o-HS(C6H4)CO2H) was synthesized from three different ligand-exchange reactions, as 3 without any solvate or as 3a with CH2Cl2 solvate, in good yield. The complex 3 can be interconverted with the previously obtained, two antimicrobially-active silver(I) thiosalicylates; one was the oligomeric, water-soluble complex {Na[Ag(tsa)] · H2O}n, 1 (n=21-27) and the other the polymeric, water-insoluble complex [Ag(Htsa)]n, 2. The analogous gold(I) complex [Au(Htsa)(PPh3)], 4, was also isolated. The complexes 3, 3a and 4 were characterized with complete elemental analyses, TGDTA, FT-IR and multinuclear NMR (1H, 13C, 31P and 10;Ag) spectroscopies. The crystal structures of 3 and 4 were determined with single-crystal X-ray diffraction. The monomeric structure for 3 and the dimeric structure via hydrogen bonds of the carboxylic acid for 4 in the solid state were found.
