Lanthanide Complex Based on Urea Ligand as Homogeneous Catalyst

A new lanthanide-coordination complex containing ۱,۳-di(pyrimidin-۲-yl)urea (LH) linker, namely[La(LH)₂Cl₂(MeOH)₂]·H₂O, was synthesized and characterized using X-ray crystallography and spectroscopicmethods. In this compound, two LH ligands are coordinated from pyrimidine nitrogens and urea oxygens to thelanthanum metal, with two LH ligands for each lanthanum metal. In the structure of this complex, the LH ligandacts as a bidentate, and a metal-ligand complex is formed with a ratio of ۱:۲. Crystallographic studies of thestructure of this compound show that it crystallizes in Pī space group of the triclinic system. This compound canbe a promising homogeneous catalyst for organic transformations.
