Lanthanum carbonate, La 2 (C O 3) 3, is the salt formed by lanthanum(III) cations and carbonate anions. It is an ore of lanthanum metal ( bastnäsite ), along with monazite . Chemistry
Lanthanum acetate is an inorganic compound, a salt of lanthanum with acetic acid with the chemical formula La(CH 3 CO 2) 3. According to X-ray crystallography, anhydrous lanthanum acetate is a coordination polymer. Each La(III) center is nine-coordinate, with two bidentate acetate ligands and the remaining sites occupied by oxygens provided by ...
The CuTi 2 structure of the lanthanum, cerium and praseodymium diiodides along with HP-NdI 2 contain 4 4 nets of metal and iodine atoms with short metal-metal bonds (393-386 La-Pr). [10] these compounds should be considered to be two-dimensional metals (two-dimensional in the same way that graphite is). The salt-like dihalides include those of ...

Lanthanum acetylacetonate refers to the coordination complex with the formula La(C 5 H 7 O 2) 3. This anhydrous acetylacetonate complex has not been characterized well, but the dihydrate La(C 5 H 7 O 2) 3 (H 2 O) 2 has been characterized by X-ray crystallography. [2] [3] Upon heating under vacuum, the dihydrate converts to the oxo-cluster La 4 ...
The anhydrous compound can be produced by heating the hydrates to 300 °C. If heated further, anhydrous lanthanum(III) sulfate decomposes to La 2 O 2 SO 4 at 775 °C, which in turn decomposes to lanthanum(III) oxide at 1100 °C.
Lanthanum carbonate was approved as a medication (Fosrenol, Shire Pharmaceuticals) to absorb excess phosphate in cases of hyperphosphatemia seen in end-stage kidney disease. [71] Lanthanum fluoride is used in phosphor lamp coatings. Mixed with europium fluoride, it is also applied in the crystal membrane of fluoride ion-selective electrodes. [17]
The lanthanide trichlorides can generally be prepared by dissolving the oxide or carbonate with hydrochloric acid. They are produced commercially by carbothermic reaction of the oxide. To produce the anhydrous forms of these trichlorides, the ammonium chloride route is taken. The anhydrous lanthanide trichlorides have high melting points and ...
