Abstract
The magnetic susceptibility Of [Cu4OCl6-nBrnL4] type tetranuclear complexes (L=morpholine) has been recorded and analysed using models that account fo r a decreased symmetry. Although the structural distortions are rather low, a symmetry descent to S-4 is ultimate for a successful fitting of the magn etic data. On a systematic substitution of Cl for Br atoms a decrease of th e 'intradimer' coupling constants is registered. (C) 2001 Elsevier Science B.V. All rights reserved.
