Zirconium acetylacetonate is the coordination complex with the formula Zr(C5H7O2)4. It is a common acetylacetonate of zirconium. It is a white solid that exhibits high solubility in nonpolar organic solvents, but not simple hydrocarbons. The complex is prepared by treating zirconium oxychloride with acetylacetone: ZrOCl2 + 4 Hacac → Zr(acac)4 + 2 HCl + H2O More volatile than Zr(acac)4 is the related complex of 1,1,1-trifluoroacetylacetonate.

dbo:abstract
  • Acetylacetonát zirkoničitý je komplexní sloučenina se vzorcem Zr(C5H7O2)4, acetylacetonátový komplex zirkonia. Jedná se o bílou pevnou látku dobře rozpustnou v nepolárních organických rozpouštědlech, ovšem ne v jednoduchých uhlovodících. Připravuje se reakcí s acetylacetonem: ZrOCl2 + 4 Hacac → Zr(acac)4 + 2 HCl + H2O Molekula má grupu symetrie D2, komplex je tedy chirální. Obdobný 1,1,1-trifluoracetylacetonátový komplex je těkavější než Zr(acac)4. (cs)
  • Zirconium acetylacetonate is the coordination complex with the formula Zr(C5H7O2)4. It is a common acetylacetonate of zirconium. It is a white solid that exhibits high solubility in nonpolar organic solvents, but not simple hydrocarbons. The complex is prepared by treating zirconium oxychloride with acetylacetone: ZrOCl2 + 4 Hacac → Zr(acac)4 + 2 HCl + H2O The complex has a square antiprismatic geometry with eight nearly equivalent Zr-O bonds of length 2.19 Å. The molecular symmetry is D2, i.e. the complex is chiral. Compounds of high coordination number tend to be stereochemically nonrigid as indicated by the observation of one methyl signal by proton NMR spectroscopy. More volatile than Zr(acac)4 is the related complex of 1,1,1-trifluoroacetylacetonate. (en)
  • 乙酰丙酮锆是一种配位化合物,化学式为Zr(C5H7O2)4,或简写为Zr(acac)4。它是白色固体,在非极性有机溶剂中有着高溶解度,但在一般的烃类溶剂中溶解度较差。 该配合物可由氧氯化锆和乙酰丙酮反应得到: ZrOCl2 + 4 Hacac → Zr(acac)4 + 2 HCl + H2O 它有方形反棱柱几何结构,包含8个几乎等价的Zr-O键,键长2.19 Å;分子的对称性群为D2,即它是手性分子。高配位数的化合物倾向于非刚性的立体结构,这由质子NMR光谱法观察到的一个甲基信号所示。 Zr(acac)4的相关物种配体的类似物更具挥发性。 (zh)
