Abstract
The asymmetric unit of the title compound, [Cu(2)Cl(4)(C(15)H(14)N(4))(2)], contains two halves of two centrosymmetric dinuclear mol-ecules, A and B. The conformations of the two crystallographically independent mol-ecules are slightly different: in A, the Cu⋯Cu 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 mol-ecule, the copper(II) ions have a distorted trigonal-bipyramidal coordination geometry with a CuCl(2)NN'N'' chromophore. The crystal packing exhibits weak inter-molecular C-H⋯Cl inter-actions.Keywords
