Palladium diarsenide is an inorganic compound with the chemical formula PdAs2. It is one of the arsenides of palladium.
Preparation
Palladium 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]
