| Abstract: A new centrosymmetric hexanuclear iron(Ⅲ) complex [NaFe6L6(MeO)6]Cl has been synthesized from the tridentate Schiff base ligand 2-[1-(2-hydroxyethylimino)ethyl]phenol (H2L) and sodium dicyanamide with iron(Ⅲ) chloride in methanol. The complex was characterized by elemental analyses, infrared spectroscopy, and X-ray single crystal determination. The crystal of the complex crystallizes as triclinic space group P1, with a=1.162 5(2) nm, b=1.396 4(2) nm, c=1.504 2(2) nm, α=66.154(7)°, β=68.809(7)°, γ=73.296(7)°, V=2.053 6(5) nm3, Z=1, R1=0.059 3, wR2=0.156 4. Thermal stability and antimicrobial activity of the complex were studied. CCDC: 889111. |
