Syntheses of new organo-lanthanide complexes [(CH3OCH2CH2C5H4)2LnCl]2 and their XPS

Abstract The substituted cyclopentadienyl sodium salt CH 3 OCH 2 CH 2 C 5 H 4 Na reacts with LnCl 3 (Ln = La, Nd, Gd, Ho, Er, Yb and Y) in THF at room temperature to give the new complexes [(CH 3 OCH 2 CH 2 C 5 H 4 ) 2 LnCl] 2 in good yield. XPS (X-ray photoelectron spectroscopy) studies show that the metals in these complexes are coordinated through the oxygen atoms.
