Abstract
Crystals of Eu-(Gly-Gly-Gly) (H2O)5.(ClO4)3 are triclinic, spacegroup P with a = 9.123 (2), b = 11.185 (5), c = 11.426 (2) Å; α = 90.79 (2), β = 98.08 (1), γ = 98.57 (2)°; Z = 2. The europium cation is surrounded by four oxygens from three different peptide units and four oxygens from water molecules. The geometry around the metal is a distorted bi-capped trigonal prism. The peptide backbone conformation in this complex is compared with those in the free peptide and in various metal complexes. Considerable differences are observed between Eu(III) and Ca(II) complexes of triglycine.
