Terbium(III) nitrate is an inorganic chemical compound, a salt of terbium and nitric acid, with the formula Tb(NO3)3. The hexahydrate crystallizes as triclinic colorless crystals with the formula [Tb(NO3)3(H2O)4]·2H2O.[1] It can be used to synthesize materials with green emission.[2]

Preparation[edit]

Terbium(III) nitrate can be prepared by dissolving terbium(III,IV) oxide in a mixture of aqueous HNO3 and H2O2 solution.[3]

Terbium(III) nitrate can be obtained by reacting terbium(III) oxide with nitric acid and crystallizing then drying the crystals with 45~55% sulfuric acid to obtain the hexahydrate.[4]

Properties[edit]

It reacts with NH4HCO3 to produce Tb2(CO3)3 along with its basic carbonate.[5] It forms Tb(NO3)2−5 in CH3CN with excess nitrate anions.[6]
