Abstract: Each Cu^II atom in the title complex, [Cu₂Cl₄(tpen)], where tpen is N,N,N',N'-tetrakis(2-pyridylmethyl)-1,2-ethanediamine (C₂₆H₂₈N₆), is clearly five-coordinate with approximate square-pyramidal geometry. Four of the coordinating atoms, viz. a Cl atom and the three N atoms of a tpen ligand, lie in a distorted square plane around Cu^II. The second Cl atom occupies the apical position of the square pyramid. The Cu-Cl distances are 2.262  (1) and 2.478  (1)  Å, and the Cu-N distances are 2.006  (4) to 2.089  (4)  Å.
