Synthesis and Structural Characterization of Hexacoordinate Silicon, Germanium, and Titanium Complexes of the E-coli Siderophore Enterobactin
The E. coli siderophore enterobactin, one of the strongest Fe-III chelators known to date, is also capable of binding Si-IV under physiological conditions. We report on the synthesis and structural characterization of the tris(catecholate) Si-IV-enterobactin complex and its Ge-IV and Ti-IV analogues. Comparative structural analysis, supported by quantum-chemical calculations, reveals the correlation between the ionic radius and the structural changes in enterobactin upon complexation.
