Synthesis, Structure Evaluation, Spectroscopic and Antibacterial Investigation of Metal Complexes with 2-(Pyridin-4-yl)quinoline-4-carboxylic acid

Four metal complexes based on quinoline carboxylate ligand from 2-(pyridin-4-yl)quinoline-4-carboxylic acid (HL), {[ML2(H2O)2]∙2H2O}n (M = MnII, 1; M = CoII, 2; M= CdII, 3) and {[Ag2L2(H2O)2]∙3H2O}n (4) have been synthesized under hydrothermal conditions. Their structures were determined by elemental analyses, IR spectra, and further characterized by single-crystal X-ray diffraction analysis. Complexes 1–3 feature a 1D chain structure which is further linked together to construct the 3D supramolecular network through hydrogen bonds. Complex 4 exhibits a 3D configuration. The fluorescent behavior and antibacterial activities of these compounds have been investigated.
