摘要
The centrosymmetric dinuclear compound of formula [Cu(mu-N-3-kappa N1)(N-3-kappa N1)(bbmp)12 is reported. Synthesis, characterization, physical properties are determined in detail, together with its 3D structure. The dinuclear end-on azide-bridged copper(II) compound displays a weak antiferromagnetic interaction, despite the fact that the magnetic orbitals overlap. The Cu-Cu contact distance is 3.1867(8) angstrom, while the Cu-N-azide-Cu angle is 103.41(14)degrees The IR spectra of the azido ligands are as expected for such coordinated azides.
