Synthesis, crystal structure, and luminescence properties of a three-dimensional coordination polymer from europium(iii) carbonate hemioxalate hydrate

Abstract

A new luminescent lanthanide coordination polymer composed of europium(III), oxalate and carbonate was prepared. A hydrothermal technique was applied to an aqueous solution of europium(III) nitrate and oxalic acid (H2ox)...

Bilayered lanthanide squarate hydrates (Ln = Eu to Lu) and magnetization reversal barriers of 21 K for Ln = Tm and 57 K for Yb

“…This finding may be related to the periodic nature of the 4f-group ions. Coordination polymers containing Ln ions with small and symmetrical bridging ligands are of interest from the viewpoint of novel magnetic and other functional materials, 7–9,52 and studies of related coordination polymers are now underway.…”
