Abstract

A binuclear copper(II) complex with two symmetric end-on azido bridges: [Cu2(tacn)2(µ-N3)2](ClO4)2 · CH3OH (1), where tacn = 1,4,7-triazacyclononane, has been synthesized and structurally as well as magnetically characterized. Compound (1) has the discrete binuclear structure, bridged by two end-on N −3 anions. The macrocyclic ligand tacn functions as a terminal ligand. The magnetic data of compound (1) were analyzed by means of Ĥ = −2JŜ1Ŝ2 − DŜ z , leading to J = 2.49 cm−1, g = 2.08, D = ±0.97 cm−1, zJ′ = −0.47 cm−1. The ferromagnetic interaction is discussed on the basis of the structural features and is compared with the model structure of Ruiz.
