D. S. Cati and H. Stoeckli-Evans

Abstract: In the complex, bis[-N,N'-bis(pyridin-2-ylmethyl)pyrazine-2,3-dicarboxamide]bis[sulfatocopper(II)] hexahydrate, [Cu₂(C₁₈H₁₆N₆O₂)₂(SO₄)₂]·6H₂O, the pyrazine ligand coordinates in a tridentate-monodentate manner with the Cu atoms having N₃O₂ chromophores. A neutral centrosymmetric binuclear macrocyclic structure is formed, with the Cu atoms having almost perfect square-pyramidal geometry.
