/ˌasᵻtɪləˈsɛtəneɪt/, U.S.

/əˌsidlˈæsətnˌeɪt/,

/ˌæsədlˈæsətnˌeɪt/

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: acetylacetone n., -ate suffix¹.

Etymology: < acetylacetone n. + -ate suffix¹, after French acétylacétonate (A. Combes 1887, in Comptes rendus hebd. de l'Acad. des Sci. 105 869). Compare earlier acetonate n.In later use sometimes reanalysed as < acetyl n. + acetonate n., and hence written acetyl acetonate.

Chemistry.

A compound in which one or more acetylacetone molecules (or anions derived from them) are bonded to a metal atom, usually as bidentate ligands.
