Abstract:

N,N′-bis(L-phenylalanyl)ethane-1,2-diamine was prepared by using L-phenylalanine and ethanediamine. The synthetic process was improved. The ligand reacted with copper dichloride to form the chiral coordination compound. The single crystal was obtained in methanol solution. It is shown by X-ray structural studies that the crystal belongs to the tetragonal system and the space group is I4. The lattice parameters are as follows: a=2.504 4(4) nm, b=2.504 4(4) nm, c=0.870 7(3) nm, V=5.461(2) nm 3, Dc=1.365 g/cm3, Z=8. In the structure of the complex, the Cu(Ⅱ) cation is coordinated by two nitrogen atoms, two oxygen atoms and one chlorine atom.
