The Syntheses And Structures Of Pyrazolyl Carboxylic Acid Derivatives And Metal Coordination Polymers

Pyrazole is a kind of heterocycle compound which possesses very high activity.It was widely used in many fields such as pesticide, medicine, dyestuff andphotographic developer, It is also very important in Coordination Chemistry becauseof heterocycles containing Nitrogen Atom which has good coordination capability.Firstly, we design, synthesis and characterizate a series of pyrazolyl carboxylic acidderivatives, and then a series of pyrazolyl carboxylic acid Metal-carboxylateCoordination Polymers are synthesized using hydrothermal/solvethermal synthesismethod and characterized structure by the X-ray diffraction technology for singlecrystal. Concrete contents is as follows:1. The pyrazolyl carboxylic acid derivatives such as: 5-phenyl-1H-pyrazole-3-Carboxylic acid, 3-phenyl-1H-pyrazole-4-carboxylic acid, 1-phenyl-1H-pyrazole-3, 5-dicarboxylic acid, 5-chloro-3-methyl-1-phenyl-1H-pyrazole-4-carboxylic acid,5-chloro-1-phenyl-1H-pyrazole-3, 4-dicarboxylic acid have been synthesized andcharacterized by element analysis and FT-IR spectra and 1HNMR spectrum, etc.2. There are seven pyrazolyl carboxylic acid Metal-carboxylate CoordinationPolymers are synthesized using hydrothermal/solvethermal synthesis method, andcharacterized structure by element analysis and the X-ray diffraction technology forsingle crystal.
