Popis:	The ground state of the magnetic copper ion and the transfer of unpaired spin to the ligands is described taking into account the influence of the crystalline field and the partly covalent bonding with three inequivalent pairs of ligands. Experimentally determined (super) hyperfine interactions of all nuclei, electronic g tensor and crystal field parameters form the data on which the analysis of the covalency is based. A discussion of the super-exchange mechanisms and exchange paths in these compounds is given. From this analysis the nearest-neighbour exchange interactions are estimated in close agreement with experimental values.
