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)·H 2O(1), Cu(sal tau)·2H 2O(2) and the molecular formula of CuC 10 H 11 O 4N, CuC 9H 13 O 6NS 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= 1.4981 nm, b=1.8246nm, c=2.1985nm,V=6.0094nm 3 for 1; a=0.9454nm, b= 1.7092 nm, c=2.2254nm, V=3.5960nm 3 for 2 respectively.
