Neodymium(III) vanadate explained

Neodymium(III) vanadate is an inorganic compound, a salt of neodymium and vanadic acid with the chemical formula of NdVO₄. It forms pale-blue, hydrated crystals.

Preparation

Neodymium(III) vanadate is produced by the reaction of hot acidic neodymium(III) chloride and sodium vanadate:

NdCl _{3} +Na _{3VO} _{4} \xrightarrow{ NdVO _{4 \downarrow} + 3 NaCl}

Physical properties

Neodymium(III) vanadate forms crystals of the tetragonal crystal system, space group I 41/amd, lattice constants a = 0.736 nm, b = 0.736 nm, c = 0.6471 nm, α = 90°, β = 90°, γ = 90°, Z = 4.^[1]
