In these compounds, neodymium generally exhibits the +3 oxidation state, such as NdCl 3, Nd 2 (SO 4) 3 and Nd(CH 3 COO) 3. Compounds with neodymium in the +2 oxidation state are also known, such as NdCl 2 and NdI 2. Some neodymium compounds have colors that vary based upon the type of lighting. [1]
Neodymium(III) chloride or neodymium trichloride is a chemical compound of neodymium and chlorine with the formula NdCl 3.This anhydrous compound is a mauve-colored solid that rapidly absorbs water on exposure to air to form a purple-colored hexahydrate, NdCl 3 ·6H 2 O. Neodymium(III) chloride is produced from minerals monazite and bastnäsite using a complex multistage extraction process.

Some lanthanides (as well as scandium and yttrium) form pentachlorides: M 2 O 3 + 10 NH 4 Cl → 2 (NH 4) 2 MCl 5 + 3 H 2 O + 6 NH 3 (M = Dy, Ho, Er, Tm, Lu, Yb, Y, Sc) Tb 4 O 7 + 22 NH 4 Cl → 4 (NH 4) 2 TbCl 5 + 7 H 2 O + 14 NH 3. Other lanthanides for hexachlorides: M 2 O 3 + 12 NH 4 Cl → 2 (NH 4) 3 MCl 6 + 3 H 2 O + 6 NH 3
Neodymium(III) oxide has a low-temperature trigonal A form in space group P 3 m1. [7] This structure type is favoured by the early lanthanides. [8] [9] At higher temperatures it adopts two other forms, the hexagonal H form in space group P6 3 /mmc and the cubic X form in Im 3 m. The high-temperature forms exhibit crystallographic disorder. [10 ...

Neodymium(III) carbonate can form complexes with ammonium carbonate, sodium carbonate and potassium carbonate and many other salts, which explains their greater solubility in aqueous solutions than in distilled water. It can easily be converted into other neodymium compounds, such as neodymium(III) oxide when heated. [6]
