Syntheses and Crystal Structures of Two Isostructural Zinc(II) Complexes With Schiff-bases 2-Bromo-4-chloro-6-[(3-methylaminopropylimino)methyl]phenol and 2,4-Dichloro-6-[(3-methylaminopropylimino)methyl]phenol

摘要

Two new isostructural mononuclear zinc(II) complexes, [Zn(C11H14Cl2N2O)(NCS)(CH3COO)] and [Zn(C11H14BrClN2O) (NCS)(CH3COO)], have been synthesized from the Schiff-bases 2-bromo-4-chloro-6-[(3-methylaminopropylimino)methyl]phenol and 2,4-dichloro-6-[(3-methylaminopropylimino)methyl]phenol, respectively. Both complexes were characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The Zn atom in each of the complexes is coordinated by one phenolic oxygen atom and one imine nitrogen atom of a Schiff-base ligand, one nitrogen atom of a thiocyanate anion, and one oxygen atom of an acetate ligand, giving a tetrahedral geometry.
