Synthesis and characterization of an organometallic Schiff base and its lanthanide chelates

Summary A Schiff base containing an organometallic substituent,N, N-bis(ferrocenyl-1-oxo-3-methyl)propenyl]ethylenediamine (H₂ bfe) and its chelates with lanthanide(III), Ln(bfe)]Cl·0–1H₂O (Ln=Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, or Lu) have been prepared and characterized by elemental analyses, i.r., u.v.,¹H n.m.r., molar conductance, and t.g. analysis. The ligand is a tetradentate species and coordinates to the central lanthanide ion by the oxygen and nitrogen with 11 stoichiometry. The chelates are 11 electrolytes.
