| Abstract: | Four cadmium(II) complexes of the semirigid tridentate ligand 8-[(pyridin-4-yl)methylthio] quinoline (TQMP4, L), namely, [CdL2](ClO4)2 (1), [Cd(L)Br2] (2), [Cd2(L)2(NO3)4] (3), and [Cd2(L)2I4] (4), have been prepared by the methods of layering and the diffusing of diethyl ether. The structures of the complexes have been identified by elemental analysis (EA), infrared spectra (IR) and single-crystal diffraction. The different coordination modes of the ligands and counter anions result in a 2D (4, 4) net structure in complex 1, a 1D polymer chain in complex 2, and 0D binuclear rings in complexes 3 and 4. Their antibacterial and antifungal activities were also tested. |
