Our previous suggestion that lanthanide(III) ions form 1:3 complexes of axial symmetry with sodium (methyl α-D-galactopyranosid)uronate has been supported by further NMR studies and model building.LIS experiments also showed that the phenylmethyl glycoside forms similar complexes.Dysprosium(III)-induced 17O NMR shifts indicated that the lanthanide complexes contain three coordinated water molecules.By cooling a methanolic solution of the methyl glycoside containing Eu(3+) ions, a precipitate was formed which, it was possible to show, had 1:3 stoichiometry.
