Abstract: In the crystal structure of the title complex, [Cu₂(C₁₀H₂₀N₄O₂)(C₁₀H₈N₂)₂](ClO₄)₂, the deprotonated dmaeoxd^2- ligand {H₂dmaeoxd is N,N'-bis[2-(dimethylamino)ethyl]oxamide} occupies an inversion centre at the mid-point of the central C-C bond and is thus in a trans conformation. The two Cu^II atoms are located in slightly distorted square-based pyramidal environments. The binuclear units interact with each other via - interactions to form a one-dimensional chain extending in the c direction.

Formula: [Cu₂(C₁₀H₂₀N₄O₂)(C₁₀H₈N₂)₂](ClO₄)₂
