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 to date have been contaminated with P₂H₄ and P₄H₆ (both branched and linear isomers).[4]
