  pH-dependent self-assembly of copper(II) complexes with a new imidazole-containing polyamine ligand: Synthesis, structure and magnetic property

  摘要：

  Four copper(II) complexes were synthesized by reactions of new imidazole-containing polyamine ligand N-1-(2-aminoethyl)-N-1-(1H-imidazol-4-ylmethyl)-ethane-1,2-diamine (HL) with CU(ClO4)(2) center dot 6H(2)O under different pH and their structures were characterized by X-ray crystallography. Interestingly, the complexes have diverse structures from protonated ligand [H-3(HL)][CuCl4] center dot Cl (1), dinuclear [Cu-2(HL)(2)Cl](ClO4)(3) center dot H2O (2), one-dimensional chain polynuclear {[Cu(L](ClO4)}(n) (3) to cyclic-tetranuclear [Cu-4(L)(4)](ClO4)(4) center dot 3CH(3)CN (4) coordination compounds by varying reaction pH from acidic to basic. The results indicate that the reaction pH has great impact on the formation and structure of the complexes. The magnetic measurements show that there are antiferromagnetic interactions between the Cu(II) centers with g = 2.09,J = -39.0 cm(-1) and g = 2.17,J = -36.8 cm(-1) for 3 and 4, respectively.
