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:
Yttrium oxalate is an inorganic compound, a salt of yttrium and oxalic acid with the chemical formula Y2(C2O4)3. The compound does not dissolve in water and forms crystalline hydrates—colorless crystals.
Neodymium acetate is an inorganic salt composed of a neodymium atom trication and three acetate groups as anions where neodymium exhibits the +3 oxidation state. It has a chemical formula of Nd(CH3COO)3 although it can be informally referred to as NdAc because Ac is an informal symbol for acetate. It commonly occurs as a light purple powder.
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.
Gallium acetate is a salt composed of a gallium atom trication and three acetate groups as anions where gallium exhibits the +3 oxidation state. It has a chemical formula of Ga(CH3COO)3 although it can be informally referred to as GaAc because Ac is an informal symbol for acetate. Gallium is moderately water-soluble and decomposes to gallium oxide when heated to around 70 °C. Gallium acetate, like other acetate compounds, is a good precursor to ultra-pure compounds, catalysts and nanoscale materials. Gallium acetate is being considered as a substitute in de-icing compounds like calcium chloride and magnesium chloride.
Europium(III) acetate is an inorganic salt of europium and acetic acid with the chemical formula of Eu(CH3COO)3. In this compound, europium exhibits the +3 oxidation state. It can exist in the anhydrous form, sesquihydrate and tetrahydrate. Its hydrate molecule is a dimer.
Dysprosium acetate is a hypothetical salt of dysprosium and acetate. Its proposed chemical formula is Dy(CH3COO)3.
Holmium acetate is the acetate salt of holmium, with a chemical formula of Ho(CH3COO)3.
Erbium(III) acetate is the acetate salt of erbium, with the proposed chemical formula of Er(CH3COO)3. It can be used to synthesize some optical materials.
Terbium compounds are compounds formed by the lanthanide metal terbium (Tb). Terbium generally exhibits the +3 oxidation state in these compounds, such as in TbCl3, Tb(NO3)3 and Tb(CH3COO)3. Compounds with terbium in the +4 oxidation state are also known, such as TbO2 and BaTbF6. Terbium can also form compounds in the 0, +1 and +2 oxidation states.
Thulium(III) acetate is the acetate salt of thulium, with the chemical formula of Tm(CH3COO)3. It can exist in the tetrahydrate or the anhydrous form.
Cerium acetate is an inorganic compound with the chemical formula of Ce(CH3COO)3. It is a white powder that is soluble in water. Its 1.5 hydrate loses water at 133°C to obtain an amorphous anhydrous form, and the amorphous phase changes to crystal at 212°C, and phase changes again at 286°C.
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.
Samarium(III) acetate is an acetate salt of samarium, with the chemical formula of Sm(CH3COO)3. It exists in the hydrate and tetrahydrate form. Its tetrahydrate can be obtained by dissolving samarium(III) oxide in 50% acetic acid solution, crystallizing and vacuum drying. The mixed anion acetate [Sm(CH3COO)(H2O)6]Cl2·H2O and [Sm(CH3COO)2(H2O)3]Cl can be crystallized from SmCl3·6H2O and SmOCl in acetic acid solution respectively.
Lanthanum acetylacetonate is a coordination compound with the chemical formula La(C5H7O2)3, or abbreviated as La(acac)3. Its instability constants (logYn) are 3.65, 5.13 and 6.12 (corresponding to n=1, 2, 3). It can be prepared by the reaction of lanthanum alkoxide and acetylacetone. Its tetrahydrate decomposes into monohydrate at 110 °C, obtains the anhydrous form at 150 °C, undergoes La(CH3COO)(acac)2 and La(CH3COO)2(acac), and at 180~285 °C lanthanum acetate is produced. It can be used to prepare NaLaS2, La2Zr2O7 and other materials.
