The following complexes of iron(II) with the amino acids glycine, alanine, phenylglycine, phenylalanine, leucine, serine, aspartic acid, glutamic acid, glutamine, tryptophan, histidine, methionine, S-methylcysteine, cystine, and glycylglycine have been isolated: Fe(Gly)2, Fe(Ala)2, Fe(Phegly)2, Fe(Phe)2·2H20, Fe(Leu)2·2H20, Fe(Ser)2, Fe(Asp)·2H20, Fe(Glu)·2H20, Fe(Gln)2, Fe(Trp)2, Fe(His)2·H20 and 2H20, Fe(Met)2, Fe(MeCys)2, Fe(CysCys) and Fe(GlyGly)2. Their magnetic behaviour, reflectance spectra, and Mössbauer parameters are consistent with high spin, hexacoordinate iron(II), and imply extended structures involving carboxylate bridges. |
