Two novel complexes {(Co(A‐glu)(Im) 2 (·0.5H 2 O} n ( 1 ) and (Cd(A‐glu)(Im) 3 ( n ( 2 ) (H 2 A‐glu N ‐acetyl‐ L ‐glu‐ tamic acid, Im=imidazole) have been synthesized from the reaction of H 2 A‐glu with Co(CH 3 COO) 2 ·4H 2 O or Cd(CH 3 COO) 2 ·2H 2 O 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.
