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 ...
Although most compounds are referred to by their IUPAC systematic names ... Lanthanum(III) sulfate – La 2 (SO 4) 3; Pb
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.
Anhydrous lanthanum(III) chloride can be produced by the ammonium chloride route. [3] [4] [5] In the first step, lanthanum oxide is heated with ammonium chloride to produce the ammonium salt of the pentachloride: La 2 O 3 + 10 NH 4 Cl → 2 (NH 4) 2 LaCl 5 + 6 H 2 O + 6 NH 3
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(III) oxalate forms colorless crystals that are poorly soluble in water. [3] The compound forms various crystallohydrates La 2 (C 2 O 4) 3 •n H 2 O, where n = 1, 2, 3, 7, and 10. [4] [5] The crystallohydrates decompose when heated. [6]
