A novel end-to-end azide-bridged trinuclear Cu(II) complex [(CuIIL)3(mi1,3-N3)2](ClO4)4 has been prepared by using a macrocyclic ligand L (L = 1,3,6,9,11,14- hexa - azatricyclo[12.2.1.16,9] octadecane). The complex has been characterized by single-crys - tal X-ray diffraction analysis and magnetic measurements. The complex crystallizes in a monoclinic system, P21/n space group, with a = 9.2932(13), b = 23.398(3), c = 13.4557(19) capital A, ring, beta = 99.673(3)° and V = 2884.3(7) capital A, ring 3, that con sists of two mi 1,3-(end-to-end, EE) azide bridging ligands and three Cu(II) macrocyclic ligands, in which one of these Cu(II) macrocyclic lig ands is in an octahedron environment, and other two ones are in square-prism geometry. Magnetic measurements indicate that the complex exhibits a very weak ferromagnetic coupling between the Cu(II) centers with J = +0.20 cm–1.
