Nd(III) and Dy(III) coordination compounds based on 1H-tetrazolate-5-acetic acid ligands: Synthesis, crystal structures and catalytic properties

Abstract: Reactions of 1H-tetrazolate-5-acetic acid(H2tza) with Nd(NO3)3·6H2O or Dy(NO3)3·6H2O with the presence of KOH under solvothermal conditions, produced two new coordination compounds, [M2(tza)3(H2O)6]·2H2O [M=Nd(1), Dy(2)]. Both compounds were structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Compounds 1 and 2 reveal 1D structures via bridging tza as linker. Furthermore, the compounds 1 and 2 showed a specific and good catalytic behavior for the polymerization of styrene, and the polymerization showed controlled characteristics. [Copyright &y& Elsevier]
