Abstract: The asymmetric unit of the title compound, [Cu₂Cl₄(C₁₅H₁₄N₄)₂], contains two halves of two centrosymmetric dinuclear molecules, A and B. The conformations of the two crystallographically independent molecules are slightly different: in A, the CuCu separation is 4.174 (9) Å and the dihedral angle between the triazole and phenyl rings is 74.23 (11)°; these values are 4.137 (9) Å and 68.58 (13)°, respectively, in B. In each molecule, the copper(II) ions have a distorted trigonal-bipyramidal coordination geometry with a CuCl₂NN'N'' chromophore. The crystal packing exhibits weak intermolecular C-HCl interactions.
