Synthesis
Ytterbium(III) nitride can be prepared from the reaction of ytterbium hydride and ammonia at 800°C:[4]
- 2YbH2 + 2NH3 → 2YbN + 5H2
It can also be prepared from the reaction of ytterbium and nitrogen with an admixture of hydrogen under pressure at 500–600°C::
- 2Yb + N2 → 2YbN
Physical properties
