The saturated hydrides of tervalent arsenic, having the general formula AsnHn+2. Individual members having an unbranched arsenic chain are named arsane, diarsane, triarsane, etc. The name of a saturated @H02904@ of arsenic where one or more arsenic atoms have @B00703@ 5 is formed by prefixing locants and \(\lambda ^{5}\) symbols to the name of the corresponding arsane, e.g. H2AsAsHAsH2 triarsane, H4AsAsH3AsH4 1\(\lambda ^{5}\),2\(\lambda ^{5}\),3\(\lambda ^{5}\)-triarsane. Hydrocarbyl derivatives of AsH3 belong to the class @A00452@.
