The saturated hydrides of tervalent phosphorus having the general formula PnHn+2. Individual members having an unbranched phosphorus chain are named phosphane, diphosphane, triphosphane, etc. The name of a saturated @H02904@ of phosphorus wherein one or more phosphorus atoms have a @B00703@ of 5 is formed by prefixing locants and \(\lambda ^{5}\) symbols to the name of the corresponding phosphane. Hydrocarbyl derivatives of PH3 belong to the class @P04553@.
