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.

For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.
