| Abstract: | Eleven transition metal complexes of three asymmetrical tridentate thioether ligands, 8-((pyridin-2-yl)methylthio) quinoline (TQMP2), 8-((pyridin-3-yl)methylthio) quinoline (TQMP3), 8-((pyridin-4-yl)methylthio) quinoline (TQMP4) and one symmetrical pentadentate ligand 2,6-bis (8-quinolinylthiomethyl) pyridine (DTQMP) were prepared. The structures of all these complexes were identified by means of elemental analysis (EA), infrared spectra (IR) and single-crystal diffraction, providing three different kinds of basic conformations, (1) discrete mononuclear structures, (2) dinuclear rings and (3) 1D polymer chains. The antibacterial, antifungal and pesticide activities of the four ligands and 11 complexes were also studied. |
