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 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(III) iodide is very soluble in water and is deliquescent. [4] Anhydrous lanthanum(III) iodide reacts with tetrahydrofuran to form a photoluminescent complex, LaI 3 (THF) 4, with an average La–I bond length of 3.16 Å. [6] [7] This complex is a starting material for amide and cyclopentadienyl complexes of lanthanum. [6] [8]
Lanthanum fluoride is insoluble in water and can be used as a qualitative test for the presence of La 3+. The heavier halides are all very soluble deliquescent compounds. The anhydrous halides are produced by direct reaction of their elements, as heating the hydrates causes hydrolysis: for example, heating hydrated LaCl 3 produces LaOCl. [38]
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 ...
