Acetylacetone is a weak acid. It forms the acetylacetonate anion C5H7O− 2 (commonly abbreviated acac−): C5H8O2 ⇌ C5H7O− 2 + H+ The structure of the acetylacetonate anion (acac−) In the acetylacetonate anion, both C - O bonds are equivalent.

Acetylacetonate | C5H7O2- | CID 5460482 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

Typically both oxygen atoms bind to the metal to form a six-membered chelate ring. The simplest complexes have the formula M (acac) 3 and M (acac) 2. Mixed-ligand complexes, e.g. VO (acac) 2, are also numerous. Variations of acetylacetonate have also been developed with myriad substituents in place of methyl (RCOCHCOR ′ −). [1]

Acetylacetonate is a compound that serves as a gelation agent in zirconia sol-gel reactions by acting as a chelating agent, inhibiting dehydration reactions, and stabilizing Zr-based colloids to facilitate the formation of nanoparticles and zirconia gel.

Acetylacetonate (acac -, top) is an anionic bidentate ligand that coordinates metal ions through two oxygen atoms. Acac - is a hard base so it prefers hard acid cations.

2017年12月30日 · Metal acetylacetonate complexes are used in different applications; for example, as catalyst in chemical transformations such as oligomerization, polymerization, hydrogenation, isomerization of alkynes, coupling of organic halides and trans-esterifications.

The article provides a suitable platform for students to produce a complex of metal acetylacetonate, interpret the keto-enol tautomerization of acetylacetone, and ultimately quantify the compound’s electronic structure by means of the …

this interest, many metal acetylacetonates were studied during World War II and during the Cold War, including their crystal structures.3 Interestingly and probably because of classification of scientific data of importance to the military, the earliest structural description of an uranium acetylacetonate appearing in the Cambridge Structural

2022年1月1日 · The present work focuses on the characterization of the electronic structure of the transition metal acetylacetonate, TM (AcAc) n (TM = Cr, Fe, Co, Ni, Cu; n = 1, 2, 3), through both qualitative approach and ab initio methodologies.

In practice, the existence of the free anion, commonly abbreviated acac−, is a useful model. Coordination chemistry The acetylacetonate anion forms complexes with many transition metal ions wherein both oxygen atoms bind to the metal to form a six-membered chelate ring.
