Abstract
The reaction of N-[(S)-1-phenylethyl]-N-[1-(2-pyridinyl)methyl]amine (PEPMA) with Zn(ClO4)2 affords (PEPMA)2Zn(ClO4)2 at room temperature. The complex is characterized by elemental analysis, 1H-MNR and X-ray crystallography. The crystal system is orthorhombic with space group of P212121 and unit cell parameters: a = 8.6911(4), b = 9.7755(7), c = 37.275(2) Å, V = 3166.9(3) Å3, Z = 4, Dx = 1.445 Mg/m3. The crystal structure reveals that zinc metal is ligated by two PEPMA ligands in a distorted tetrahedral fashion. Interestingly, both nitrogen atoms of amine at PEPMA to the central zinc metal exhibit (R)-configuration.Index AbstractThe X-ray structure study reveals that the coordination of zinc(II) perchlorate and N-[(S)-1-phenylethyl]-N-[1-(2-pyridinyl)methyl]amine (PEPMA) ligand affords the zinc(II) complex in a distorted tetrahedral geometry and induces new chiral centers at both amine-nitrogens of PEPMA ligands in (R)-configuration .
