Vanadyl(IV) sulfate describes a collection of inorganic compounds of vanadium with the formula, VOSO4(H2O)x where 0 ≤ x ≤ 6. The pentahydrate is common. This hygroscopic blue solid is one of the most common sources of vanadium in the laboratory, reflecting its high stability. It features the vanadyl ion, VO2+, which has been called the "most stable diatomic ion".
Chromium(III) acetylacetonate is the coordination compound with the formula Cr(C5H7O2)3, sometimes designated as Cr(acac)3. This purplish coordination complex is used in NMR spectroscopy as a relaxation agent because of its solubility in nonpolar organic solvents and its paramagnetism.
Aluminium acetylacetonate, also referred to as Al(acac)3, is a coordination complex with formula Al(C5H7O2)3. This aluminium complex with three acetylacetone ligands is used in research on Al-containing materials. The molecule has D3 symmetry, being isomorphous with other octahedral tris(acetylacetonate)s.
Barium acetylacetonate is a compound with formula Ba(C5H7O2)2. It is the Ba2+ complex of the anion acetylacetonate. The compound is typically encountered as an ill-defined hydrate, which would accord with the high coordination number characteristic of barium.
Cerium(III) acetylacetonate is a compound with formula Ce(C5H7O2)3(H2O)x. It is typically isolated as the trihydrate. Partial dehydration gives the dihydrate, a red-brown solid.
Dysprosium acetylacetonate is a chemical compound of dysprosium with formula Dy(C5H7O2)3(H2O)n.

Gadolinium acetylacetonate is a compound with formula Gd(C5H7O2)3(H2O)2. It is a gadolinium(III) complex with three acetylacetonate and two aquo [[ligand.
Rhodium acetylacetonate is the coordination complex with the formula Rh(C5H7O2)3, which is sometimes known as Rh(acac)3. The molecule has D3-symmetry. It is a yellow-orange solid that is soluble in organic solvents.
Zirconium acetylacetonate is the coordination complex with the formula Zr(C5H7O2)4. It is a common acetylacetonate of zirconium. It is a white solid that exhibits high solubility in nonpolar organic solvents, but not simple hydrocarbons.
Platinum(II) bis(acetylacetonate) is the coordination compound with the formula Pt(O2C5H7)2, abbreviated Pt(acac)2. The homoleptic acetylacetonate complex of platinum(II), it is a yellow, benzene-soluble solid. According to X-ray crystallography, the Pt center is square planar. The compound is a widely used precursor to platinum-based catalysts.
An yttrium compound is a chemical compound containing yttrium. Among these compounds, yttrium generally has a +3 valence. The solubility properties of yttrium compounds are similar to those of the lanthanides. For example oxalates and carbonates are hardly soluble in water, but soluble in excess oxalate or carbonate solutions as complexes are formed. Sulfates and double sulfates are generally soluble. They resemble the "yttrium group" of heavy lanthanide elements.
Yttrium oxalate is an inorganic compound, a salt of yttrium and oxalic acid with the chemical formula Y2(C2O4)3. The compound does not dissolve in water and forms crystalline hydrates—colorless crystals.
Sodium acetylacetonate is an organic compound with the nominal formula Na[CH(C(O)CH3)2]. This white, water-soluble solid is the conjugate base of acetylacetone.
Neodymium(III) acetylacetonate is a coordination compound of neodymium and acetylacetone, with the chemical formula Nd(O2C5H7)3(H2O)2, although some sources ignore the aquo ligands. It commonly occurs as a white powder.
Erbium acetylacetonate is a coordination compound, with the chemical formula of Er(C5H7O2)3, or Er(acac)3 for short.
Lanthanum acetylacetonate usually refers to the coordination complex with the formula La(C5H7O2)3(H2O)2. This species is the dihydrate of the hypothetical anhydrous acetylacetonate complex with the formula La(C5H7O2)3.
Lutetium acetylacetonate is a coordination compound with the chemical formula Lu(C5H7O2)3, or Lu(acac)3 for short. It is isomorphic to ytterbium acetylacetonate. It can be prepared by the reaction of trialkoxylutetium and acetylacetone.
Ytterbium(III) acetylacetonate is a coordination compound with the chemical formula Yb(C5H7O2)3(H2O)2. Its structure is different from the acetylacetone complexes of neodymium, europium and holmium. The adjacent Yb-Yb The distance is 8.3 Å. Yb(acac)3(bpy) can be obtained by reacting its trihydrate with 2,2'-bipyridine in ethanol.
