Abstract: The title complexes were synthesized and the crystal structures of their salts were determined by single crystal X-ray structure analyses. Na2[ZnⅡ(ida)2]·7H2O: Triclinic, P1, a =0.5234(2) nm, b =0.89710(10) nm, c =1.06910(10) nm, α =85.910(10)°, β = 76.380(10)°, γ =83.52(2)°, V =0.4842(2) nm3, Z =1. The complex anion [ZnⅡ(ida)2]2- has a pseudo octahedral structure in which the two Natoms are in a trans configuration. Na4[HgⅡ(nta)2] ·7H2O: Monoclinic, Cc, a =1.7980(4) nm, b =0.8929(2) nm, c = 1.5754(2) nm, β =92.78(3)°, V =2.5262(9) nm3, Z =4. The complex anion [HgⅡ(nta)2]4- has a pseudo bicapped octahedral structure in which the two Natoms are in a trans configuration.

Key words: ZnⅡ, HgⅡ, Aminodiacetate, Aminotriacetate, Complex
