Compounds [{Ag(phen)(mu-tu)}(2)](NO3)(2) (1), [{Ag(phen)(mu-tu)}(2)](CF3SO3)(2) (2), [{Ag(bpy)(mu-tu)}(2)](NO3)(2) (3) (where phen = 1,10-phenanthroline; bpy = 2,2'-bipyridine; tu = thiourea) were prepared by reacting the appropriate AgX salt (X- = NO3-, CF3SO3-), the N,N-chelating ligand (phen or bpy) and thiourea in a ca. 1:1:2 M ratio, respectively. The silver(l) complexes were characterized by elemental analysis, infrared (IR), H-1 and C-13 NMR spectroscopies, MS/ESI and conductivity measurements. The IR and NMR data were consistent with the presence of chelating phen (1 and 2) and bpy (3) ligands and demonstrated the S-coordination mode of thiourea. The crystal and molecular structures of compound [{Ag(bpy)(mu-tu)}(2)] (NO3)(2) (3) were determined by single-crystal X-ray diffraction. The complexes 1-3 were screened for their in vitro antimycobacterial (Mycobacterium tuberculosis), antileishmanial (Leishmania (L) amazonensis), antibacterial (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa), antifungal activities (Candida albi cans, Candida tropicalis, Candida krusei).
