Synthesis and crystal structure of novel 2,5-difluorophenylphosphonic acid disodium salt

The novel 2,5-difluorophenylphosphonic acid disodium salt was synthesized from 2,5-difluoroaniline by diazotization,reacted with phosphorus trichloride,then hydrolyzed and neutralized.The structure of the novel compound was characterized by 1H NMR,31P NMR,elemental analysis and X-ray single crystal diffraction analysis.
