Solvothermal Synthesis,Structure And Properties Of Compound?PyH?[Cu₂?ttc?]

Heterocyclic thione have attracted considerable interest as ligands in metal compounds because of their applications in physical and chemical properties such as catalysts,biological activity,semiconductor materials,solar energy conversion,and so on.Therefore,the synthesis of new sulfides is a research hotspot in the filed of coordination chemistry.There are describing several methods about the synthesis of sulfides and the achievement in this filed.The synthesis methods of sulfides are solvent-assisted,solid-phase,electrochemical,and solvothermal/hydrothermal.Compare to the other methods,solvothermal technique not only reaction condition is mild,but also most of novel compounds can be produced.Water and non-aqueous all will display a critical or supercritical state which can increase the reactivity in this conditions.However,transition metal ions is prone to form the less solubility of transition metal sulfide in the process of synthesizing heterocycles under solvothermal condition,therefore the number of known synthetic heterocycles containing transition metal ions is limited.The key of successfully obtain novel structure is to search for suitable mineralizer to increase the solubility of transition metal sulfide under mild solvothermal condition.When introduced a suitable mineralizer,the solubility of the transition metal sulfide can be increased.It will avoid the appearing the precipitate in direct.We successfully synthesized compound?PyH?[Cu₂?ttc?].On the basis of this work,the compounds of Zn²⁺,Cd²⁺,Ni²⁺,Pb²⁺containing heterocycle with smooth surfaces,sharp edges and corners were further explored and obtained.The single-crystal test and the characterization of the structure and properties are underway.The layered compound?PyH?[Cu₂?ttc?]was solvothermally synthesized with the presence of thiophenol mineralizer.From the result of single crystal diffraction,we can find it belong to Triclinic system.Crystal data for compound?PyH?[Cu₂?ttc?]:Mr=382,space group1?,a=7.6824?12??,b=7.8094?13??,c=9.9541?18??,V=555.95?16??.The Cu?I?atoms totally have planar triangular coordination.The compound?PyH?[Cu₂?ttc?]shows strong fluorescence by the solid fluorescence test analysis.The compound?PyH?[Cu₂?ttc?]also shows high thermal stability.
