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

Silver(I) pyridinecarboxylates (AgPIC (1), AgNIC (2), Ag(HDIPIC)]·0.75H₂O (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 Δ(ν_as???ν_s) comparisons were accomplished. In addition, silver(I) pyridinecarboxylate antimicrobial activities and stability by ¹H NMR spectra were determined. Moreover, the spectral, thermal, and antimicrobial properties of silver(I) and previously prepared zinc(II) pyridinecarboxylates were compared and discussed.
