Abstract
The copper(II) complex [Cu(L)(en)2]2[Cu(en)2](L)2(ClO4)6, L = 4-2-pyridine-1,2,4-triazole, en = ethylenediamine has been prepared and characterized. Crystals are triclinic, space group P [image omitted] with Z = 1, a = 8.637(3), b = 13.850(4), c = 16.295(5) Å, α = 106.662(6), β = 104.039(6), γ = 97.616(6)°, V = 1768.4(10) Å3. The structure of the title compound consists of three independent cations with two five-coordinate [Cu(L)(en)2] units and a four-coordinated [Cu(en)2] unit with two weak axial Cu-N interactions to lattice ligand molecules (2.552 Å). Other physical properties are described. Both the ligand and the complex fluoresce with different luminescent process.
