Abstract: Bis(N,N-dimethylethylenediamine)copper(II) oxalate dihydrate, [Cu(C₄H₁₂N₂)₂](C₂O₄)·2H₂O, has been synthesized. Both the cation and anion are centrosymmetric. The Cu atom is in a distorted square geometry, coordinated by the four N atoms of the bidentate ligands. There are long [2.583  (2)  Å] axial contacts to water. The crystal structure of the complex has a two-dimensional structure through hydrogen bonding.
