Abstract

Conclusions The diprotic, tetradentate ligand 1, 5-bis [(1, 2-dihydro-l-hydroxy-2-oxopyridin-6- yl) carbonyl]-1, s-diazapentane (5) reacts with ferric ion to form a Fe2L3 complex. In the solid state this complex has the triply-bridged structure 7,(Figure 1). The iron-complexing ability of 5 at neutral pH resembles that of the dihydroxamate siderophore rhodotorulic acid (6). Unlike rhodotorulic acid or other hydroxamate ligands (including desferrioxamine B, the ...
