Neodymium bismuthide or Bismuth-Neodymium is a binary inorganic compound of neodymium and bismuth with the formula NdBi. It forms crystals.
Europium compounds are compounds formed by the lanthanide metal europium (Eu). In these compounds, europium generally exhibits the +3 oxidation state, such as EuCl3, Eu(NO3)3 and Eu(CH3COO)3. Compounds with europium in the +2 oxidation state are also known. The +2 ion of europium is the most stable divalent ion of lanthanide metals in aqueous solution. Many europium compounds fluoresce under ultraviolet light due to the excitation of electrons to higher energy levels. Lipophilic europium complexes often feature acetylacetonate-like ligands, e.g., Eufod.
Neodymium(III) phosphate is an inorganic compound, with the chemical formula of NdPO4. Its hemihydrate can be obtained by the reaction of neodymium(III) chloride and phosphoric acid; its anhydrous form can be obtained by the reaction of silicon pyrophosphate (SiP2O7) and neodymium(III) fluoride. It reacts with calcium pyrophosphate to obtain Ca9Nd(PO4)7.
Sodium hexachloroiridate(III) is an inorganic compound with the chemical formula Na3IrCl6.
Scandium perrhenate is an inorganic compound, with the chemical formula Sc(ReO4)3. Its thermal stability is lower than that of the corresponding compounds of the yttrium and lanthanum perrhenates.
Gallium perrhenate is an inorganic compound with the chemical formula of Ga(ReO4)3. It exists in the anhydrous and hydrate forms.
Gadolinium perrhenate is an inorganic compound, with the chemical formula of Gd(ReO4)3. It can be obtained by dissolving an excess of gadolinium oxide in a perrhenic acid solution (240 g/L) in the presence of hydrogen peroxide, from which the hydrates are precipitated. Its tetrahydrate loses water by heating to obtain the anhydrous form, which then decomposes at high temperatures to generate gadolinium oxide and rhenium heptoxide.
Praseodymium acetylacetonate is a coordination compound with the chemical formula Pr(C5H7O2)3, or Pr(acac)3 for short. Its instability constants (logYn) are 2.89, 4.17 and 5.29 (corresponding to n=1, 2, 3). It can be prepared by the reaction of trialkoxypraseodymium and acetylacetone. When praseodymium chloride reacts with sodium acetylacetonate or lithium acetylacetonate in the solid phase, praseodymium acetylacetonate can also be obtained, but NaPr(acac)4 or LiPr(acac)4 will also be generated. It can form the green complex Pr(acac)3(phen) with o-phenanthroline.
Lithium tellurite is an inorganic compound, with the chemical formula Li2TeO3. It crystallises in the monoclinic crystal system, with space group C2/c. It can be prepared by reacting lithium oxide, lithium hydroxide or lithium carbonate with tellurium dioxide. It reacts with lithium fluoride at high temperatures in a 3:1 stoichiometric ratio to obtain Li7(TeO3)3F.

It reacts with arsenic triselenide to obtain DyAsSe3.
Praseodymium bromide is an inorganic compound with the chemical formula Pr(BrO3)3. It is soluble in water and can form the dihydrate, tetrahydrate and nonahydrate. The nonahydrate melts in its own crystal water at 56.5 °C and completely loses its crystal water at 130 °C. It can be produced by the reaction of barium bromate and praseodymium sulfate.
Thulium(III) selenate is an inorganic compound, with the chemical formula Tm2(SeO4)3. It can be obtained by reacting a thulium(III) oxide and selenic acid solution and crystallizing it. It crystallises with ammonium selenate in an aqueous solution to obtain NH4Tm(SeO4)2·3H2O.
