Lanthanum(III) nitrate is any inorganic compound with the chemical formula La(NO 3) 3 ·xH 2 O. It is used in the extraction and purification of lanthanum from its ores. [5] The compound decomposes at 499°C to lanthanum oxide, nitric oxide and oxygen. [3]
Lanthanum nitride can be prepared from the reaction of nitrogen and lanthanum trihydride: 2LaH 3 + N 2 → 2LaN + 3H 2. It can also be prepared from the reaction of ammonia and lanthanum trihydride: [3] LaH 3 + NH 3 → LaN + 3H 2. The reaction of nitrogen and lanthanum amalgam can also work: [4] 2La + N 2 → 2LaN

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 usually occurs together with cerium and the other rare earth elements. Lanthanum was first found by the Swedish chemist Carl Gustaf Mosander in 1839 as an impurity in cerium nitrate – hence the name lanthanum, from the ancient Greek λανθάνειν (lanthanein), meaning 'to lie hidden'.
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]
The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
