SYNTHESIS AND CHARACTERIZATION OF MIXED-LIGAND COMPLEXES OF Co(II), Ni(II), and Cu(II) WITH SOME TRIAZOLES AND AMINO ACIDS
摘要:
Mixed-ligand ternary metal complexes of some divalent transition metal ions [Cu(II), Ni(II) and Co(II)] with triazole compounds [1,2,4-triazole (TRZ) and 3-mercapto-1,2,4-triazole (TRZSH)] and dicarboxylic amino acids, H2L, (aspartic and glutamic) have been synthesized. The prepared ternary chelates were characterized by elemental and thermogravimetric analyses, IR and electronic spectra as well as conductivity measurements. The general formulas [M(TRZ)(L)]H2O and H[M(TRZS)(L)H2O]H2O were found for the ternary chelates containing TRZ and TRZSH, respectively.
