Three hexakis(imidazole)metallo complexes of Co, Cd and Ni were synthesized and spectroscopically characterized. The crystal and molecular structures have been determined by X‐ray crystallography analysis. The metal ions have an octahedral geometry with the MN 6 chromophore. The electrochemical experimental results indicate that both [Co(Im) 6 ]Cl 2 ·2HCl·2H 2 O ( 1 ) and [Ni(Im) 6 ]Cl 2 ·4H 2 O ( 3 ) [Imimidazole] could interact with DNA mainly by intercalation.
