Synthesis and X-Ray Crystal Structures of Two New Zinc(II) Complexes with Schiff Bases

Abstract

Two Schiff base compounds, 2-[(3-dimethylaminopropylimino)methyl]phenol (L1) and 2-bromo-4-chloro-6-[(3-methylaminopropylimino)methyl]phenol (L2), react with zinc bromide in methanol solutions, respectively, to give two mononuclear complexes, [ZnBr₂L1] (1) and [ZnBr₂L2]· 0.5H₂O (2). Both complexes were characterized by physico-chemical and spectroscopic methods. X-ray crystallography indicates that the Zn atom in each complex is in a tetrahedral coordination.
