Salicylaldoxime: An old ligand with new faces

The paper is concerned with the interactions of salicylaldoxime with trivalent transition metal ions to yield di-, tri-, tetra- and hexanuclear complexes together with their low-lying electronic structures. Tri- and tetranuclear complexes are found to exhibit spin frustration. The importance of isostructural series of compounds with varyingdn electron configurations is indicated. Relevance of some of these compounds as models for metalloproteins is also shown.
