L-aspartic acid zinc was synthesized by a rapid and convenient method in high yield under microwave conditions, and its single crystal structure was analyzed by X-ray diffraction. The structure unit of the title compound is [Zn(L-Asp)(H2O2)]·H2O, Which is a bicyclo-complex forming a spiral linear polymer via coordination bonds. The spiral linear polymers are assembled as a three-dimensional supramolecule by intermolecular hydrogen bonds. The crystal belongs to the orthorhormbic crystal system, P2(1)2(1)2(1) space group, a=0.7830(3)nm, b=0.9369(4)nm, c=11.599(5)nm,α=β=γ=90.00,V=0.8509(6)nm3,Z=4,Dc=1.955g/cm3,F(000)=512,μ=2.289. The toxicity of the title compound is lower than that of glutamic acid zinc and zinc sulfate.
