Monomeric (DME)<sub>2</sub>Ln(OC<sub>6</sub>F<sub>5</sub>)<sub>3</sub> (Ln = Nd, Er, Tm) adopt seven coordinate structures with two chelating DME and three terminal phenoxide ligands. Both (py)<sub>4</sub>Er(OC<sub>6</sub>F<sub>5</sub>)<sub>3</sub> and (THF)<sub>3</sub>Yb(OC<sub>6</sub>F<sub>5</sub>)<sub>3</sub> were also prepared and structurally characterized, with the latter being a <i>mer</i>-octahedral compound with bond lengths that are geometry dependent. Emission experiments on crystalline powders of the Nd(III), Tm(III), and Er(III) DME derivatives show that these compounds are highly emissive near-infrared sources.
