Abstract
The copper atom in acetatoaqua[[(4-methylimidazol-5- yl)methylene]histamine]-copper(II) perchlorate (1) is N,N,N-chelated by the [(4-methylimidazol- 5-yl)methylene]histamine [Cu–N=1.969(3) ∼2.019(3) Å] donor ligand. The aqua ligand occupies the apical site of the square-pyramidal coordination polyhedron [Cu–O= 2.365(3) Å], whose fifth site is occupied by the carboxy oxygen atom of the monodentate acetato anion [Cu–O=1.960(3)Å]. Cyclic voltammetry in MeCN and N,N-dimethylformamide (DMF) gives a voltage of −0.39 and −0.37 V versus s.c.e, which compares well with the value obtained for Cu,Zn superoxide dimuthase itself.
