Y.-M. Sun, J.-M. Shi and Z. Liu

Abstract: In the title mononuclear Cu^II complex, [CuBr₂(C₆H₈N₂O₂)₂], the Cu^II atom assumes a tetrahedrally distorted square-planar coordination geometry. Two Br^- anions and two methylmethoxypyrazine oxide ligands (mmpo) coordinate in a cis manner to the Cu^II atom, with a dihedral angle of 34.60 (16)° the between the Cu/Br/Br and Cu/O/O planes.
