Abstract
The temperature dependence of the magnetic susceptibility and the EPR spectra of carene-bis(μ-perchlorato)[bis(μ-imidazolato)bis(perchlorato) octakis(imidazole)tricopper(II)] showed that the compound behaves like a chain of weakly coupled trinuclear species; the best fit of the experimental points showed that the magnetic coupling between the internal and the external copper(II) atoms in the trinuclear unit is given by J = 116.9 (9) cm-1 (J is defined through the Hamiltonian H = JS1·S2). This value is compared to those previously reported for other imidazolato-bridged copper(II) complexes. © 1984 American Chemical Society.File | Dimensione | Formato | |
