Crystallographic, Electrochemical, and Pulsed EPR Study of Copper(II) Polyimidazole Complexes Relevant to the Metal Sites of Copper Proteins(,).

Copper(II) complexes of the following polyimidazole ligands have been synthesized: bis(imidazol-2-yl)methane (BIM), bis(imidazol-2-yl) ketone (BIK), 4-(imidazol-4-ylmethyl)-2-(imidazol-2-ylmethyl)imidazole (TRIM), bis[4-(imidazol-4-ylmethyl)imidazol-2-yl]methane (TIM), and bis[4-(imidazol-4-ylmethyl)imidazol-2-yl] ketone (TIK). Their crystal structures have been determined using X-ray diffraction. [Cu(ClO(4))(2)(BIM)(2)], 1, belongs to the triclinic space group P&onemacr; system, a = 7.
