The synthesis and crystal structure of imidazolate-bridged [Cu(tern)(im)Zn(tren)](ClO4)3·MeOH (tren = tris(2-aminoethyl)amine; im = imidazolate]
Abstract
The reaction of [Cu(tren)](ClO4)2[tren = tris(2-aminoethyl)amine] with [Zn(tren)](ClO4)2 and imidazole in alkaline MeOH–H2O solution gives imidazolate-bridged [Cu(tren)(im)Zn(tren)](ClO4)3·MeOH (im = imidazolate) which is similar to the active centre of superoxide dismutase as shown by X-ray crystallography.
