New silver(I) pyridinecarboxylate complexes: synthesis, characterization, and antimicrobial therapeutic potential

Silver(I) pyridinecarboxylates (AgPIC (1), AgNIC (2), [Ag(HDIPIC)]Greek ano teleia0.75H(2)O (3), PIC = picolinate, NIC = nicotinate, HDIPIC = dipicolinate) were prepared by solvothermal syntheses and their characterization were completed by elemental, spectral, and thermal analyses. To assign the pyridinecarboxylate coordination mode in the complexes, detailed mid-infrared spectral data and Delta(nu(as )- nu(s)) comparisons were accomplished. In addition, silver(I) pyridinecarboxylate antimicrobial activities and stability by H-1 NMR spectra were determined. Moreover, the spectral, thermal, and antimicrobial properties of silver(I) and previously prepared zinc(II) pyridinecarboxylates were compared and discussed.
