Magnetism in coordination complexes

Two lanthanide complexes, Ln2(Ileu)4(ClO4)6 · 8H2O, were synthesized in aqueous solution (where Ln  Nd or Er, Ileu = l-isoleucine). The crystal structure of the neodymium complex was determined by X-ray diffraction. The complex is a binuclear molecule, each neodymium ion is coordinated by four carboxylic oxygen atoms from four l-isoleucine and four oxygen atoms from H2O, forming a square antiprism coordination polyhedron.
