D. S. Cati and H. Stoeckli-Evans

Abstract: In the complex, bis[-N,N'-bis(pyridin-2-ylmethyl)pyrazine-2,3-dicarboxamido(2-)]dicopper(II) octahydrate, [Cu₂(C₁₈H₁₆N₆O₂)₂]·8H₂O, the pyrazine ligand coordinates in a tridentate-bidentate manner as L^2-. A neutral centrosymmetric binuclear macrocyclic structure is formed, with the Cu atoms having extremely distorted square-pyramidal geometry.
