Abstract Coordination polymers of Cu(II), Ni(II), CO(II), Mn(II), Zn(II), oxovanadium (IV), and dioxouranium(VI) with 2-hydroxy-4-methoxyacetophenone thiourea trioxane polymer were synthesized. Elemental analyses of the coordination polymers indicate a metal-to-ligand ratio of 1:2. The diffuse reflectance spectra and magnetic moments of coordination polymers show a distorted octahedral structure. Infrared spectral studies show that the metals are coordinated through the oxygens of carbonyl and phenolic groups and the nitrogen of thioamide group. Thermal stabilities of coordination polymers were determined by thermogravimetric analysis. Semiconducting behavior of the polymer and its coordination polymers was also studied by electrical conductivity measurements at different temperatures.
