Lanthanum nitrate, La(NO3)3






Lanthanum nitrate, La(NO3)3.6H2O, forms deliquescent, triclinic crystals which lose 5H2O over sulphuric acid. At 25° a saturated aqueous solution of the hexahydrate contains 151.1 parts of anhydrous salt per 100 of water. Lanthanum nitrate is isodimorphous with bismuth nitrate.

Lanthanum caesium nitrate, La(NO3)3.2CsNO3.2H2O, forms monoclinic crystals (a:b:c = 1.3052:1:0.9663; β = 103°26').

Lanthanum rubidium nitrate, La(NO3)3.2RbNO3.4H2O, has been described.

Lanthanum potassium nitrate, La(NO3)3.2KNO3.2H2O, forms orthorhombic crystals (hemimorphic; a:b:c = 0.5306:1:0.5696) of density 2 54 at 0° C.

Lanthanum sodium nitrate, La(NO3)3.2NaNO3.H2O, forms monoclinic crystals (a:b:c = 1.9970:1:0.7678; β = 90°32') of density 2.63 at 0° C.

Lanthanum thallium nitrate, La(NO3)3.2TlNO3.4H2O, has been prepared.

Acid lanthanum rubidium nitrate, La(NO3)3.RbNO3.HNO3.6H2O, has been prepared by Jantsch and Wigdorow. When heated to 120° it loses nitric acid and water, leaving the salt La(NO3)3.RbNO3.H2O.
