Synthesis and Structural Characterization of the Schiff Base Zn(II) Complex from Salicylaldehyde and Tris(2-aminoethyl)amine

The pentadentate N 4 O-type Schiff base ligand was obtained by the condensation reaction of salicylaldehyde and tris(2-aminoethyl)amine, and its novel Zn(II) complex [Zn 2 (C 13 H 21 N 4 O)]Cl 3 was synthesized. The compounds were characterized by IR, UV–Vis, 1 H-, 13 C-NMR spectroscopy. Crystal str...

Description
Summary:The pentadentate N 4 O-type Schiff base ligand was obtained by the condensation reaction of salicylaldehyde and tris(2-aminoethyl)amine, and its novel Zn(II) complex [Zn 2 (C 13 H 21 N 4 O)]Cl 3 was synthesized. The compounds were characterized by IR, UV–Vis, 1 H-, 13 C-NMR spectroscopy. Crystal structure of the complex was determined by X-ray single crystal diffraction. Complex crystallizes in the monoclinic system with sp. gr. P 2 1 / c and shows the ligand coordinated to two Zn ions with different structures around metal ions. One Zn(II) ion is five-coordinated: its coordination polyhedron is intermediate between trigonal bipyramid and square pyramid, being 30.1% along the pathway from trigonal bipyramid to square pyramid. Another Zn(II) ion has a tetrahedral structure. The electronic spectrum of the complex showed ligand to metal charge-transfer bands.
