Tetrajoddifosfan (P2I4) je anorganická sloučenina fosforu a jodu. Za běžných podmínek se jedná o oranžovou krystalickou látku s redukčními účinky. Atom fosforu má chemický NMR posun okolo +100 ppm (pod kyselinou fosforečnou), resp. +108 ppm v sirouhlíku. V této sloučenině má fosfor málo obvyklé oxidační číslo +2. (cs) رباعي يوديد ثنائي الفوسفور هو مركب كيميائي ينتمي إلى هاليدات الفوسفور، صيغته P2I4، ويوجد على شكل صلب بلوري ذي لون برتقالي إلى أحمر. (ar) Phosphor(II)-iodid ist eine chemische Verbindung mit der Summenformel P2I4. Sie besteht aus zwei Phosphoratomen in der Oxidationsstufe +2, die über eine Einfachbindung miteinander verbunden sind. Jedes Phosphoratom besitzt des Weiteren zwei Bindungen zu Iodatomen. (de) Diphosphorus tetraiodide is an orange crystalline solid with the formula P2I4. It has been used as a reducing agent in organic chemistry.
