Bis[?-3-ethyl-4-phenyl-5-(2-pyrid-yl)-4H-1,2,4-triazole]bis-[dichloridocopper(II)].

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.
