Abstract
The preparation, spectroscopic properties and crystal structure of [pyrrolidinium][Co(sulfathiazole)3(pyrrolidine)] are reported. The X-ray structure reveals tetrahedral geometry around cobalt. Three sulfathiazole ligands (each in a κ,N-binding mode) occupy three positions, while the remaining position is occupied by a disordered pyrrolidine. A pyrrolidinium is also disordered. The superoxide dismutase mimetic activity of the complex was investigated using the indirect xanthine-xanthine oxidase-nitroblue tetrazolium method and compared to that of the native enzyme.
