The complete mol-ecule of the title complex, [Cu(2)(C(13)H(19)N(2)O(2))(2)(N(3))(2)], is generated by the application of a centre of inversion. The central Cu(2)N(2) core is a rhombus as the μ(2)-azide ligands bridge in an asymmetric fashion. Each Cu(II) atom is also coordinated by a monoanionic tridentate Schiff base ligand via the anti-cipated oxide O, imine N and amine N atoms. The resulting...
