The Dinuclear Cu (II) complex [{CuCl}2(μ – tppz)](PF6)2, where tppz represents tetra-2-pyridinylpyrazine, has been prepared and characterized by elemental analysis, 1H-NMR, IR and UV-vis spectroscopies. A crystal structure of the complex showed the Cu (II) are surrounded by three N atoms of tppz bridging ligand and one Cl atom. Crystal structure data are as follows: crystal system monoclinic, s...
