The reaction of Sm[N(SiMe)](THF) with 2 equiv of the bulky aryloxide ligand HOAr [Ar = -CH-2,6-(CH-2,4,6- Pr)] afforded the first monomeric homoleptic solvent-free bis(aryloxide) lanthanide complex Sm(OAr ). The complex was characterized by crystallography and UV-visible and IR spectroscopy and magnetically by Evans' method. The O-Sm-O angle is highly bent at 111.08(9)°. The samarium ion in Sm(OAr ) also displays close contacts with the flanking aryl rings of the terphenyloxide ligands. The complex is paramagnetic at room temperature with a magnetic moment of 3.51 μ.
