Triphosphane (IUPAC systematic name) or triphosphine is an inorganic compound having the chemical formula HP(PH2)2. It can be generated from diphosphine but is highly unstable at room temperature:[3]

2 P2H4 → P3H5 + PH3

Samples have been isolated by gas chromatography. The compound rapidly converts to PH3 and the cyclophosphine cyclo-P5H5.[4]
