Synthesis, Crystal Structures and Properties of Two Novel Co(II) and Cd(II) Complexes of N-Acetyl-L-glutamic Acid and Imidazole Ligands
Abstract
Two novel complexes {(Co(A-glu)(Im)2(·0.5H2O}n (1) and (Cd(A-glu)(Im)3(n (2) (H2A-gluN-acetyl-L-glu- tamic acid, Im=imidazole) have been synthesized from the reaction of H2A-glu with Co(CH3COO)2·4H2O or Cd(CH3COO)2·2H2O in the presence of Im. Both of the complexes display different coordination environment and similar one-dimensional chain structure. The magnetic susceptibility measurements for 1 show a weak antiferromagnetic interaction between two cobalt(II) ions bridged by A-glu ligand. The complex 2 exhibits an intense fluorescent emission in solid state at room temperature.
