Thulium(II) chloride is an inorganic compound with the chemical formula TmCl2.
Thulium(II) chloride can be produced by reducing thulium(III) chloride by thulium metal: [1]
Thulium(II) chloride reacts with water violently, producing hydrogen gas and thulium(III) hydroxide. When thulium(II) chloride first touches water, a light red solution is formed, which fades quickly. [1]
Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Like the other lanthanides, the most common oxidation state is +3, seen in its oxide, halides and other compounds; however, the +2 oxidation state can also be stable. In aqueous solution, like compounds of other late lanthanides, soluble thulium compounds form coordination complexes with nine water molecules.
Thulium(III) chloride or thulium trichloride is as an inorganic salt composed of thulium and chlorine with the formula TmCl3. It forms yellow crystals. Thulium(III) chloride has the YCl3 (AlCl3) layer structure with octahedral thulium ions.

Thulium(III) hydroxide is an inorganic compound with the chemical formula Tm(OH)3.
Terbium(IV) fluoride is an inorganic compound with a chemical formula TbF4. It is a white solid that is a strong oxidizer. It is also a strong fluorinating agent, emitting relatively pure atomic fluorine when heated, rather than the mixture of fluoride vapors emitted from cobalt(III) fluoride or cerium(IV) fluoride. It can be produced by the reaction between very pure terbium(III) fluoride and xenon difluoride, chlorine trifluoride or fluorine gas:
Neptunium(III) chloride or neptunium trichloride is an inorganic compound with a chemical formula NpCl3. This salt is strongly radioactive.
Neodymium compounds are compounds formed by the lanthanide metal neodymium (Nd). In these compounds, neodymium generally exhibits the +3 oxidation state, such as NdCl3, Nd2(SO4)3 and Nd(CH3COO)3. Compounds with neodymium in the +2 oxidation state are also known, such as NdCl2 and NdI2. Some neodymium compounds have colors that vary based upon the type of lighting.
Neodymium(III) carbonate is an inorganic compound where neodymium is in the +3 oxidation state and the carbonate ion is in the -2 oxidation state. It has a chemical formula of Nd2(CO3)3. The anhydrous form is purple-red, while the octahydrate is a pink solid. Both of these are insoluble in water.
Praseodymium(III) perchlorate is the perchlorate salt of praseodymium, with the chemical formula of Pr(ClO4)3.
Praseodymium(III) carbonate is an inorganic compound, with a chemical formula of Pr2(CO3)3. The anhydrous form is olive green, and many of its hydrates such as heptahydrate and octahydrate are known. They are all insoluble in water.
Europium compounds are compounds formed by the lanthanide metal europium (Eu). In these compounds, europium generally exhibits the +3 oxidation state, such as EuCl3, Eu(NO3)3 and Eu(CH3COO)3. Compounds with europium in the +2 oxidation state are also known. The +2 ion of europium is the most stable divalent ion of lanthanide metals in aqueous solution. Lipophilic europium complexes often feature acetylacetonate-like ligands, e.g., Eufod.
Terbium compounds are compounds formed by the lanthanide metal terbium (Tb). In these compounds, terbium generally exhibits the +3 oxidation state, such as TbCl3, Tb(NO3)3 and Tb(CH3COO)3. Compounds with terbium in the +4 oxidation state are also known, such as TbO2 and BaTbF6.
Thulium(III) iodide is an iodide of thulium, with the chemical formula of TmI3. Thulium(III) iodide is used as a component of metal halide lamps.
