A new copper(II) coordination compound with the ligand 2,2′-bipyridine-N-oxide (abbreviated as bpyNO), Cu(bpyNO)2(CF3SO3)2, is described. This compound is investigated in detail by spectroscopy, EPR and X-ray crystal structure analysis. The compound crystallizes in the monoclinic space group P21/n with a = 6.554(1) Å, b = 13.681(3) Å, c = 14.935(3) Å, β = 98.77(3)°, Z = 2. The copper has an axial elongated octahedral geometry with the basal plane formed by two trans-orientated bpyNO molecules with Cu_N distance of 2.008(2) Å and a Cu_O distance of 1.950(2) Å. The axial positions are occupied by oxygen atoms of two trans-oriented triflate anions with a Cu_O distance of 2.397(2) Å.
