Hafnium acetylacetonate, also known as Hf(acac)4, is a coordination compound with formula Hf(C5H7O2)4. This white solid is the main hafnium complex of acetylacetonate. The complex has a square antiprismatic geometry with eight nearly equivalent Hf-O bonds. The molecular symmetry is D2, i.e., the complex is chiral. It is prepared from hafnium tetrachloride and acetylacetone, and base. Zr(acac)4 is very similar in structure and properties.

  • Acetylacetonát hafničitý, zkráceně Hf(acac)4, je komplexní sloučenina se vzorcem Hf(C5H7O2)4, hafničitý komplex s acetylacetonátovými ligandy. Jeho grupa symetrie je D2, takže je komplex chirální. Připravuje se reakcí s acetylacetonem a zásadou. Strukturou i vlastnostmi se mu podobá acetylacetonát zirkoničitý, Zr(acac)4. (cs)

  • L'acétylacétonate d'hafnium, ou Hf(acac)4, est un complexe d'hafnium(IV) et d'acétylacétone H3C–CO–CH2–CO–CH3. On l'obtient par mélange de tétrachlorure d'hafnium HfCl4 et d'acétylacétone en milieu basique. Sa structure et ses propriétés sont très peu différentes de celles de l'acétylacétonate de zirconium. À l'instar du (TBT), l'acétylacétonate d'hafnium est utilisé comme catalyseur pour la production de polytéréphtalate de butylène (PBT). (fr)
  • 乙酰丙酮铪是一种配合物,白色固体,化学式Hf(C5H7O2)4,又可记为Hf(acac)4。此为乙酰丙酮的主要铪配合物。该分子具有D2对称性。可由四氯化铪、乙酰丙酮和碱来制备。Zr(acac)4在结构和性能上与它非常相似。 (zh)
