Synthesis, Characterization, Electrochemistry, Photoluminescence and Magnetic Properties of a Dinuclear Erbium(III)-Containing Monolacunary Dawson-Type Tungstophosphate: [{Er(H ₂O)(CH ₃COO)(P ₂W ₁₇O ₆₁)} ₂] ¹⁶⁻

Abstract

Reaction of the trilacunary Wells−Dawson anion {α-P ₂W ₁₅O ₅₆} ¹²⁻ with Er ^III ion in a 1 M LiOAc/HOAc buffer (pH 4.8) solution produces a dinuclear erbium(III) substituted sandwich-type structure [{Er(H ₂O)(CH ₃COO)(P ₂W ₁₇O ₆₁)} ₂] ¹⁶⁻ ( 1). The isolated compound was structurally characterized using single crystal and powder X-ray diffraction, FTIR spectroscopy, mass spectrometry and thermogravimetric analysis. The electrochemical, electrocatalytic, photoluminescence and magnetic properties of 1 were investigated.
