Ligands containing oxygen donors play a significant role in lanthanide chemistry. The coordination chemistry of phosphine oxides with lanthanide ions has attracted interests for their applications in the extraction of lanthanide ions and functional materials. We have studied various unidentate and multidentate phosphine oxide ligands in stabilizing cationic lanthanide complexes. A series of mononuclear lanthanide complexes supported by bidentate phosphine oxide ligands have been synthesized and structurally characterized. Here we introduce the preparation and molecular structure of the cationic lanthanide complex in the formula of [Ln(dppmO2)4][X]3 (X = anion).
