Acetylacetone/Formula
Why is acetylacetonate a bidentate ligand?
Acetylacetonate ion contains two O atoms which allow this ligand to function as a bidentate ligand.
Is acetylacetonate a strong field ligand?
An easy way to identify this: The ligands in which the donor atom is Nitrogen and carbon is a strong field ligand and the ligand in which the donor atom is a halogen or oxygen is a weak field ligand. So in acac the donating atoms are Oxygen making it a weak field whereas in NH3 the donating is N making it strong field.
What is acac ligand?
Metal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH. 3COCHCOCH − 3) and metal ions, usually transition metals. The bidentate ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring.
Is Acetylacetonate a base?
Acid–base properties Acetylacetone is a weak acid: C 5H 😯 2 ⇌ C 5H 7O−2 + H.

Is Acetylacetonate an acid or base?
Acid–base properties Acetylacetone is a weak acid: C 5H 😯 2 ⇌ C 5H 7O−2 + H. IUPAC recommended pKa values for this equilibrium in aqueous solution at 25 °C are 8.99 ± 0.04 (I = 0), 8.83 ± 0.02 (I = 0.1 M NaClO 4) and 9.00 ± 0.03 (I = 1.0 M NaClO 4; I = Ionic strength).
Why is acac 3 diamagnetic?
The 1H-NMR spectrum of Co(acac)3 (Figure 4) has sharp resonances much like the aluminium complex. From this it can be determined that the complex is diamagnetic. Octahedral Co(III) centres have two possible electron configurations, high spin or low spin (Figure 5).
What is acac?
Acetylacetonate (acac), a ligand in coordination chemistry derived from acetylacetone.
Why is ACAC 3 diamagnetic?
What is nature of acetylacetone?
Acetylacetone is an organic compound with the chemical formula CH 3COCH 2COCH 3. It is a colorless liquid, classified as a 1,3-diketone. It exists in equilibrium with a tautomer CH 3C(O)CH=(OH)CH 3. It is a colorless liquid that is a precursor to acetylacetonate anion (commonly abbreviated acac−), a bidentate ligand.
