In this research, two novel compounds in which alkylenedithiomethylene Malonic acid act as the main coordination agents and the compounds containing N atom (such as pyridine, Phenanthroline Ethanediamine and 4,4'-Bipyridinyl) act as the associating coordination agents have been synthesized by the means of solution and solid-liquid diffusing reactions. 9 coordination complexes and polymers have been designed and synthesized in which the transition metals Cu and Zn acted as the centre ions. These compounds have been characterized by X-ray single crystal diffraction analysis, and some properties of them have been tested and analyzed.
