Proposed terminal carboxylate crosslinking of marinobactin E by the added cations Zn(II), Cd(II), La(III) or excess Fe(III). The bis-bidentate coordination geometry of the two carboxylates that is depicted here could also be bis-monodentate crosslinking. The identity of ligand, L, has not been established conclusively; EXAFS data is consistent with a light-atom ligand such as H2O or OH−
