UNSYMMETRIC COMPARTMENTAL LIGANDS FOR METALLOBIOSITE MODELLING: A MINI REVIEW

摘要

Studies on bimetallic complexes have received increasing attention recently because of their interesting physicochemical properties arising from the presence of two dissimilar metal ions in close proximity. Adjacent metal centers with hard-soft combination result co-operative effects that show unique reactivity patterns towards substrate molecules. New dinucleating ligands may be synthesized that feature two distinct binding pockets. These systems proved suitable for the preparation of unsymmetric bimetallic complexes in a controlled and predetermined fashion. This review describes the targeted synthesis, reactivity and structural properties of homo- and heterobinuclear complexes.
