Abstract: The title complex, [Cu₂(C₆H₂N₃O₇)₂(C₈H₁₆N₄O₂)(CH₃OH)₂], contains a centrosymmetric binuclear unit in which the oxamide ligand (at a centre of symmetry) acts in a bis-tridentate fashion and the picrate anion binds to copper(II) in a bidentate mode. The Cu^II atom displays a distorted octahedral coordination with axial elongation. The binuclear molecules are linked by hydrogen bonds, forming a three-dimensional supramolecular architecture.
