Samarium(III) fluoride (SmF3) is a slightly hygroscopic solid fluoride. Conditions/substances to avoid are: open flame, moisture, strong acids.
Samarium(III) oxide (Sm2O3) is a chemical compound. Samarium oxide readily forms on the surface of samarium metal under humid conditions or temperatures in excess of 150°C in dry air. Similar to rust on metallic iron, this oxide layer spalls off the surface of the metal, exposing more metal to continue the reaction. The oxide is commonly white to off yellow in color and is often encountered as a highly fine dust like powder.
Samarium(III) bromide is a crystalline compound of one samarium and three bromine atoms with the chemical formula of SmBr3. Samarium(III) bromide is a dark brown powder at room temperature. The compound has a crystal structure isotypic to that of plutonium(III) bromide.
Thorium(IV) hydroxide is an inorganic compound with a chemical formula Th(OH)4.
Cerium(IV) hydroxide, also known as ceric hydroxide, is an inorganic compound with the chemical formula Ce(OH)4. It is a yellowish powder that is insoluble in water but soluble in concentrated acids.
Iron(II) cyanide is an inorganic compound with the empirical formula Fe(CN)2. It may have a Fe2[Fe(CN)6] structure.
Praseodymium(III) hydroxide is an inorganic compound with a chemical formula Pr(OH)3.
Neodymium(III) hydroxide is an insoluble inorganic compound with the chemical formula Nd(OH)3.
Thulium(II) chloride is an inorganic compound with the chemical formula TmCl2.
Europium(III) hydroxide is an inorganic compound with a chemical formula Eu(OH)3.
Erbium(III) hydroxide is an inorganic compound with chemical formula Er(OH)3.
Dysprosium(III) hydroxide is an inorganic compound with the chemical formula Dy(OH)3.
Yttrium(III) hydroxide is an inorganic compound and an alkali with the chemical formula Y(OH)3.
Thulium(III) hydroxide is an inorganic compound with the chemical formula Tm(OH)3.
Terbium(III) hydroxide is an inorganic compound with chemical formula Tb(OH)3.
Samarium(III) nitrate is an odorless, white-colored chemical compound with the formula Sm(NO3)3. It forms the hexahydrate, which decomposes at 50°C to the anhydrous form. When further heated to 420°C, it is converted to the oxynitrate, and at 680°C it decomposes to form samarium(III) oxide.
Neodymium(III) carbonate is an inorganic compound, a salt, 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 salts are 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. Many europium compounds fluoresce under ultraviolet light due to the excitation of electrons to higher energy levels. Lipophilic europium complexes often feature acetylacetonate-like ligands, e.g., Eufod.
Erbium compounds are compounds containing the element erbium (Er). These compounds are usually dominated by erbium in the +3 oxidation state, although the +2, +1 and 0 oxidation states have also been reported.
Holmium(III) hydroxide is an inorganic compound with the chemical formula Ho(OH)3.
