The Synthesis Structure And Properties Of Organometallic Complexes With Sulfur Donor Ligands

This theme is to synthesize and analyze the structure and properties of nitrogenheterocyclic ligands and sulfur ligand metal-organic coordination polymers. It iswell-known that the conformation, connectivity, metal ligand ratio, dimensionalityand packing in the final product depend on the experimental conditions, such assolvents、 concentration、temperature among other things. By now, the metal-organiccoordination polymers have been the hot-topic, because of their special spacemultidimensional and characters. And these make them have great applicationprospects and measureless potential economic benefits.there have been increasing research interests focused on tetrazolate complexes.This is mainly because tetrazole compounds as polydentate N-donor ligands withdiverse coordination modes, can build a variety of metal-organic coordinationpolymers. Three new metal-organic coordination polymers is reported in the secondchapter which based on classical Keggin and Wells-Dawson type polyoxometalateand dimercapto tetrazole have been synthesized under hydrothermal conditions, andstructurally characterized by elemental IR、 TG、 XPRD and single crystal X-raydiffractions.Based on the ligand number of coordination site, ability of coordination, Predict-tability of structure, we design a new ligand named5,5′-(Disulfanediyl)Bis-(1-methyl-1H-tetrazole). Because lots of sulfur and nitrogen atoms. In the5,5′-(Disulfanediyl)Bis(1-methyl-1H-tetrazole) can coordination with different mentalion nitrogen atomscoordination ability more strong, sulphur could steady mentalion. In view of5,5′-(Disulfanediyl)Bis-(1-methyl-1H-tetrazole) coordination characteristics, The subjectis to synthesize and analyze Structure novel and properties superior of metal-organiccoordination.
