Synthetic and Spectroscopic Studies of Polymeric Metal Complexes Involving 1,4-[5-Disulphonyl-8-Hydroxyquinoline]piperazine

The polymeric metal complexes of CoII, NiII, CuII, ZnII, CdII , CeIII, LaIII and UO2II with 1,4-[5-disulphonyl-8-hydroxyquinoline]piperazine have been synthesized. It has been found that the ligand coordinates to the metal ion as a bibasic tetradentate chelating agent and can form polymeric metal complexes. The structure of the isolated metal complexes is supported by chemical analysis, thermoanalytical data, and conductivity measurements, as well as uv-visible, 1H-NMR, and IR spectroscopy. The stoichiometry of these metal complexes is M:L=2:3. A tetrahedral stereochemical configuration is suggested for the polymeric metal complexes with the exception of the CeIII and LaIII complexes, which form six-coordinate polymeric metal complexes.
