A new Schiff base 2-[3-chloropyridin-2-yl) hydrazonemethyl]-6-ethoxyphenol (HL) and its new iron(III) complex have been synthesized and characterized by elemental analysis, IR spectra, and single-crystal X-ray determination. The Schiff base was crystallized in the triclinic space group P (1) over bar, and the complex was crystallized in the monoclinic space group Cc. The particular interest is to study the coordination behavior of the Schiff base with iron. Single-crystal X-ray diffraction indicated that the Schiff base ligand coordinates to the Fe atom through the phenolate O, imine N, and py...
