A number of macrocyclic dicopper(II) complexes containing aza-, amino or amido nitrogen and phenolic oxygen donors are described, X-ray crystal structures of several of these compounds are discussed. An account of their electrochemical behaviour and magnetic properties is given. Factors that affect electron transfer behaviour with regard to stabilization of the lso- and mixed-valence species, intramolecular electron transfer, and spin-exchange interactions have been examined in terms of the structural features.

Until recently, expressions derived for the probability distribution of the magnitudes of structure amplitudes have been valid only for the range from zero up to two or three times the average magnitude. Recent progress in obtaining results valid for larger structure amplitudes (up to unitary structure factors approaching unity) is reviewed; the methods employed include Fourier-series representations, steepest-descents approximations, and computer simulations. Except for the last, the results are valid only for the space group {ie335-02}, though those for the space groups belonging to the point group 2/m and possibly some other centro-symmetric groups of low symmetry are expected to behave similarly.
