Sv. Kryatov et al., A dinuclear iron(III) complex with a bridging urea anion: implications forthe urease mechanism, CHEM COMMUN, (11), 2000, pp. 921-922
A novel complex [Fe-2(III)(mu-O){mu-OC(NH2)NH}(tpa)(2)](ClO4)(3) [tpa = tri
s(2-pyridylmethyl)amine] has been synthesized and fully characterized; its
formation from urea and the [Fe-2(III)(mu-O)(tpa)(2)(OH)(H2O)](3+) precurso
r in aqueous acetonitrile is a reversible multistep process.
