Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Preparation

edit

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]
