Ir-La

Ir-La (Iridium-Lanthanum) H. Okamoto The assessed Ir-La phase diagram is accepted from [74Dmi] with a change from " Ir2La3" to Ir3La5 based on recent crystal structure data and regarding the liquidus curves around Ir3La5 for consistency. Equiatomic IrLa was reported only by [74Dmi], but its crystal structure has not been reported. Because the IrRE-type compounds are not observed for other light lanthanide elements, IrLa may not exist. A possible alternative is Ir4La5, as speculated from the well-established Ir4Ce5. 59Com: V.B.
