| Summary: | A series of homoleptic rare earth (RE) complexes bearing phosphino-aryloxide ligands (<b>1-RE</b>, <b>2-La</b>) has been prepared. The complexes have been characterised using multinuclear NMR and IR spectroscopy, X-ray crystallography and elemental analysis. Structural characterisation highlighted the different RE–P interactions as a result of differing Lewis acidity and ionic size across the series, hinting at the possibility of FLP-type activity. The potential reactivity of these complexes has been tested by reacting them with small molecules (H<sub>2</sub>, CO, CO<sub>2</sub>). A series of side-products (<b>3-RE</b>) has also been observed, isolated and characterised, featuring the incorporation of a phosphonium-aryloxide ligand. |
