铁III和镓III与六齿席夫碱配体的配合物的特征在于在水溶液中。它们是由含有磺酸盐或三甲基铵基团的水杨醛与多胺在金属离子存在下缩合而成的。这些复合物在生理pH下具有与异羟肟酸铁载体复合物类似的稳定性。研究了其中两种配体从[Fe Ⅲ（edta）]-（edta =乙二胺-N，N，N′，N′-四乙酸盐）中置换Fe Ⅲ的动力学。
Complexes of FeIII and GaIII with hexadentate Schiff-base ligands have been characterised in aqueous solution. They were prepared by the condensation of salicylaldehydes, containing a sulphonate or trimethylammonium group, with polyamines in the presence of the metal ions. These complexes have stabilities, at physiological pH, similar to those of the hydroxamic acid siderophore complexes. The kinetics of the displacement of FeIII from [FeIII(edta)]–(edta = ethylenediamine-N,N,N′,N′-tetra-acetate) by two of these ligands has been studied.
