Preparation
editPalladium diarsenide can be obtained by the reaction of palladium and arsenic:[1]
- Pd + 2 As → PdAs2
In the reaction of palladium and gallium arsenide (350~800 °C), palladium disarsenide will also be formed:[2]
- 3 Pd + 2 GaAs → 2 PdGa + PdAs2
It is a cubic crystal with a = 5.983 Å.[3]
