Abstract :
The magnetic susceptibility of [Cu4OCl6−nBrnL4] type tetranuclear complexes (L=morpholine) has been recorded and analysed using models that account for a decreased symmetry. Although the structural distortions are rather low, a symmetry descent to S4 is ultimate for a successful fitting of the magnetic data. On a systematic substitution of Cl for Br atoms a decrease of the `intradimerʹ coupling constants is registered.
