Neodymium compounds

[9] Evaporating the resulting solution yields hydrated neodymium(III) nitrate, where the hexahydrate form is the most common.

[16][17] The solubility of the compound increases when sodium acetate is added, forming a blue complex.

These compounds are similar to those of the other lanthanides, characterized by an inability to undergo π backbonding.

They are thus mostly restricted to the mostly ionic cyclopentadienides (isostructural with those of lanthanum) and the σ-bonded simple alkyls and aryls, some of which may be polymeric.

[20] Neodymium(III) chloride does not have strong luminescence,[21] though it serves as a source of Nd3+ ions for various light emitting materials.

Neodymium may be used to color glass in delicate shades ranging from pure violet through wine-red and warm gray.
