Sodium acetylacetonate, Na(acac), is the precursor to many acetylacetonate complexes. A general method of synthesis is to treat a metal salt with acetylacetone in the presence of a base: [12] MB z + z Hacac ⇌ M(acac) z + z BH. Both oxygen atoms bind to the metal to form a six-membered chelate ring.
Metal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH 3 COCHCOCH − 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.
Sodium acetylacetonate is an organic compound with the nominal formula Na[CH(C(O)CH 3) 2]. This white, water-soluble solid is the conjugate base of acetylacetone. [1]
Anhydrous nickel(II) acetylacetonate exists as molecules of Ni 3 (acac) 6. The three nickel atoms are approximately collinear and each pair of them is bridged by two μ 2 oxygen atoms. Each nickel atom has tetragonally distorted octahedral geometry , caused by the difference in the length of the Ni–O bonds between the bridging and non ...
Vanadyl acetylacetonate is the chemical compound with the formula VO(acac) 2, where acac – is the conjugate base of acetylacetone. It is a blue-green solid that dissolves in polar organic solvents. The coordination complex consists of the vanadyl group, VO 2+, bound to two acac – ligands via the two oxygen atoms on each.
Tris(acetylacetonato)cobalt(III) is prepared by the reaction of cobalt(II) carbonate and acetylacetone in the presence of hydrogen peroxide: [3]. 2 CoCO 3 + 6 CH 3 COCH 2 COCH 3 + H 2 O 2 → 2 Co(O 2 C 3 Me 2 H) 3 + 2 CO 2 + 4 H 2 O
Scandium acetylacetonate is the coordination complex with the formula Sc(C 5 H 7 O 2) 3 where [C 5 H 7 O 2] − refers to acetylacetonate. It is a volatile white solid that is soluble in benzene. The complex features Sc(III) with octahedral molecular geometry. [1] It was first prepared by treating scandium nitrate with acetylacetone in the ...
In enzymology, an acetylacetone-cleaving enzyme (EC 1.13.11.50) is an enzyme that catalyzes the chemical reaction. pentane-2,4-dione + O 2 acetate + 2-oxopropanal. Thus, the two substrates of this enzyme are pentane-2,4-dione and O 2, whereas its two products are acetate and 2-oxopropanal.
