Crystal Structure and Redox Behavior of a Novel Siderophore Model System:  A Trihydroxamato−Iron(III) Complex with Intra- and Interstrand Hydrogen Bonding Networks

An iron(III) complex of a novel tripodal tris-hydroxamate, tris[2-{(N-acetyl-N-hydroxy)glycylamino}ethyl]amine (TAGE), was synthesized as a siderophore model. Its X-ray structure revealed that intra- and interstrand hydrogen bonding networks cause an increase in the iron redox potential.
