Iodine heptafluoride, also known as iodine(VII) fluoride or iodine fluoride, is an interhalogen compound with the chemical formula IF7. It has an unusual pentagonal bipyramidal structure, as predicted by VSEPR theory. The molecule can undergo a pseudorotational rearrangement called the Bartell mechanism, which is like the Berry mechanism but for a heptacoordinated system.It forms colourless crystals, which melt at 4.5 °C: the liquid range is extremely narrow, with the boiling point at 4.77 °C. The dense vapor has a mouldy, acrid odour. The molecule has D5h symmetry.

  • سباعي فلوريد اليود هو مركب كيميائي بين هالوجيني من عنصري اليود والفلور له الصيغة الكيميائية IF7، ويكون على شكل غاز عديم اللون. (ar)
  • Fluorid jodistý je anorganická sloučenina se vzorcem IF7. Patří mezi halogenidy (dokonce jde o interhalogen, tedy dvouprvkovou sloučeninu obsahující dva různé halogeny) s prvkem v oxidačním čísle VII. Jeho husté páry mají štiplavě plesnivý zápach. (cs)
  • Iodheptafluorid, auch bekannt als Iod(VII)-fluorid, ist eine chemische Verbindung aus den Elementen Iod und Fluor im Verhältnis 1:7. Es gehört zu den Interhalogenverbindungen. (de)
  • El heptafluoruro de yodo, fluoruro de yodo (VII) o fluoruro peryódico es un compuesto formado por iones de yodo y fluoruro ​ Su fórmula química es . El yodo se encuentra en su estado de oxidación +7. (es)

  • Joodheptafluoride is een interhalogeenverbinding met als brutoformule IF7. De stof komt voor als een kleurloos gas met een muffe en zure geur, dat oplosbaar is in water. (nl)
  • 七フッ化ヨウ素(ななフッかヨウそ、Iodine heptafluoride)またはフッ化ヨウ素(VII)(Iodine(VII) fluoride)は、化学式がIF7の無機化合物である。単にフッ化ヨウ素とも呼ばれる。VSEPR理論によれば五方両錐形の分子構造をとる。分子はベリー機構のようなを受ける。無色の固体で融点は4.5℃であるが液体である温度範囲は狭く、沸点は4.77℃である。濃い蒸気は強いカビ臭を持つ。 (ja)
  • L'eptafluoruro di iodio, anche conosciuto come fluoruro di iodio(VII), è il composto di formula IF7. questo composto ha un'inusuale struttura a bipiramide a base pentagonale come previsto dalla Teoria VSEPR.Forma cristalli incolori, i quali fondono a 4,5 °C: l'intervallo di temperatura della fase liquida è molto stretto, con il punto di ebollizione a 4,77 °C. I densi vapori hanno un odore acre. La molecola di IF7 non segue la regola dell'ottetto, per cui è una molecola ipervalente. (it)

  • 七氟化碘是一种无机化合物,也称作氟化碘(VII),化学式为IF7。它具有不寻常的五角双锥构型,这与价层电子对互斥理论的预测一致。七氟化碘的分子會透過機制進行原子重排,Bartell假旋轉是一種類似Berry假旋转的機制,不過只針對五角双锥构型的分子。这种无色晶体在4.5 °C时熔化,液态的温度范围非常狭窄,因为沸点只有4.77 °C。高浓度的蒸汽有发霉、刺鼻的气味。 (zh)
  • L'heptafluorure d'iode est le composé de formule IF7. Cette molécule hypervalente a une géométrie bipyramidale pentagonale peu courante. L'heptafluorure d'iode se présente sous forme d'un solide cristallin blanc qui fond à 4,5 °C mais bout dès 4,77 °C en formant une vapeur dense à l'odeur âcre de moisi. C'est un composé très irritant pour la peau et les muqueuses. (fr)
