Usage

Chemical Properties

Reddish, microcrystalline powder. Decomposes at 575C, d 2.64. Soluble in water and dilute acids.

Uses

Oxalates of the rare-earth metals are used to separate the latter from common metals. Erbium Oxalate is an important colourant in glasses and porcelain enamel glazes. High purity Erbium Oxalate is widely applied as dopant in making optical fibre and amplifier. It is particularly useful as an amplifier for fiber optic data transfer. And it has specialized uses in prosphors.

Proton conduction: Via lattice water molecules in oxalato-bridged lanthanide porous coordination polymers

The proton conducting properties of two different structural types of porous coordination polymers [La2(ox)3(H2O)6]·4H2O (1) and [Er2(ox)3(H2O)6]·12H2O (2), where ox2- = oxalate, were investigated. 1 has a two-dimensional layered structure, whereas 2 has a three-dimensional structure. Both 1 and 2 have hydrophilic one-dimensional channels filled by lattice water molecules with hydrogen-bonding networks. The coordinated H2O molecules are Lewis acidic due to the lanthanoid ions donating protons to lattice-filling H2O molecules, thereby forming efficient proton conduction pathways. Alternating-current impedance analyses of 1 and 2 indicated significant proton conduction (σ = 3.35 × 10-7 S cm-1 at 368 K for 1, 1.79 × 10-6 S cm-1 at 363 K for 2 under RH = 100%, with Ea = 0.35 eV for 1 and 0.47 eV for 2), which was attributed to the Grotthuss mechanism via the lattice H2O molecules.
