Synthesis and Characterization of Copper(Ⅱ) Complexes with Schiff Base Ligands from Salicylaldehyde and Non-natural Amino Acids

The new complexes of N-salicylidene(sal) β-alanine(β-ala) or taurine(tau) with divalent copper ion have been synthesized. The compositions and structures of the new complexes are characterized by elemental analyses, molar conductance, infrared spectra, thermogravimetric and differential thermal analysis, X-ray powder diffraction(XRD). The two complexes have the compositions of Cu(sal-β-ala)*H2O(1), Cu(sal-tau)*2H2O(2) and the molecular formula of CuC10H11O4N, CuC9H13O6NS respectively. The molar conductance data show that the complexes are nonelectrolyte. Infrared spectra and the thermal decomposition process of the complexes show the presence of coordination water molecules. Some possible thermal decomposition reactions have been proposed, and the compositions of the final residues are all cupper oxide. The results of indexes to the XRD data indicate that the crystal structure of the complexes belong to orthorhombic system, the lattice parameters are: a=1.4981nm, b=1.8246nm, c=2.1985nm,V=6.0094nm3 for 1; a=0.9454nm, b=1.7092nm, c=2.2254nm, V=3.5960nm3 for 2 respectively.
