Physical Properties
Stannid dipallady forms crystals of the rhombic syngony , the space group P nma , cell parameters a = 0.812 nm, b = 0.565 nm, c = 0.431 nm, Z = 4, the structure of the stannide type of the nickel Ni 2 Sn [1] .
The compound is formed by the peritectic reaction at a temperature of 820 ° C [1] .
In the temperature range of 1100-1287 ° C, there is a γ-Pd 3 Sn 2 phase with a composition identical to Pd 2 Sn [2] . In later works, this phase is called γ-Pd 2 Sn and it belongs to the hexagonal syngony , the space group is P 6 3 / mmc , and the structure is nickel arsenide type NiAs [3] .
