Glufosinate-phosphonic acid hydrate single crystal and preparation method thereof

The invention discloses a glufosinate-phosphonic acid hydrate single crystal and a preparation method thereof. The glufosinate-phosphonic acid hydrate single crystal belongs to an orthorhombic system,and has a space group of P2 2 2 , and the following cell parameters: alpha=90 degrees, beta=90 degrees and gamma=90 degrees, the unit cell volume is that 4 molecules of glufosinate-phosphonic acid and 4 molecules of water contained in per unit cell. The preparation method comprises the following steps: dissolving the glufosinate-phosphonic acid into a solvent, performing cooling, allowing the cooled solution to stand, slowly evaporating the solvent, and performing crystallization to obtain the glufosinate-phosphonic acid hydrate single crystal. The glufosinate-phosphonic acid hydrate single crystal provided by the invention belongs to the orthorhombic system and is a novel monohydrate crystal different from a current technology, and the preparation method is simple and has a green and environmentally-friendly pre
