A [mu]-Oxamidato-Bridged Dinuclear Copper(II) Complex

The oxen ligand [oxen = N,N'-bis(2-aminoethyl)oxamide] in the title compound, [mu]-[N,N'-bis(2-aminoethyl)oxamido(2-)-N,N', O:N'',N''',O']-bis[aqua(quinoxaline-N')copper(II)] diperchlorate, [Cu₂(C₆H₁₂N₄O₂)(C₈H₆N₂)₂(H₂O)₂](ClO₄)₂, is bis-terdentate in a trans-conformation bridging two copper(II) ions to form a centrosymmetric binuclear molecule. The symmetry-equivalent central copper(II) ions are located in a distorted square-based pyramid with a water molecule bonded at the axial site.
