The In–Pd–Sn phase diagram (xPd≤0.6): Isothermal sections

Establishing the Isostructural Platform GaPd2‐InPd2‐SnPd2 to Address Electronic and/or Structural Effects

“…In a later investigation of the system, Luef et al . observed for the first time the phase In 1‐ x Sn x Pd 2 ( x =0.44) while investigating an isothermal cut at 700 °C of the In−Pd−Sn phase diagram [9] . They found that the SnPd 2 phase possesses a high solubility for In where Sn atoms can be replaced by In up to 22 at.%.…”

“…While the isostructural series (Ga,Sn)Pd 2 has been recently established, [4] out of the other two quasi binary cuts, only the composition In 1-x Sn x Pd 2 (x = 0.44) has been previously described. [9] The SnÀ Pd phase diagram [10] shows the presence of two different phases at the composition SnPd 2 . Up to 820 °C, SnPd 2 crystallises in the Co 2 Si type of crystal structure, while at 820 °C, it decomposes peritectoidally into SnPd 3 and Sn 2 Pd 3 .…”

“…x Sn x Pd 2 (x = 0.44) while investigating an isothermal cut at 700 °C of the InÀ PdÀ Sn phase diagram. [9] They found that the SnPd 2 phase possesses a high solubility for In where Sn atoms can be replaced by In up to 22 at.%. Based on that, they suggested a continuous solubility line between the isotypic orthorhombic compounds InPd 2 and SnPd 2 in the ternary phase diagram.…”

“…The last edge (GaPd 2 ‐SnPd 2 ) corresponds to a combined alteration of electron concentration and geometric variation. While the isostructural series (Ga,Sn)Pd 2 has been recently established, [4] out of the other two quasi binary cuts, only the composition In 1‐ x Sn x Pd 2 ( x =0.44) has been previously described [9] …”

Insights into the Electronic Effects in Methanol Electro-Oxidation by Ternary In1–xSnxPd2 Intermetallic Compounds

“…Moreover, Pd–Sn − and In–Pd − catalysts showed promising catalytic properties for the oxidation of small organic molecules. InPd 2 and SnPd 2 are isostructural intermetallic compounds ( oP 12, Co 2 Si-type of crystal structure), and the isothermal section of the In–Pd–Sn phase diagram (Figure ) reveals a full substitutional series for In 1– x Sn x Pd 2 at 700 °C, which was recently revisited . The extremely small variation of the unit cell volume by only 1.3% (V­(InPd 2 ) = 195.1 Å 3 vs V­(SnPd 2 ) = 197.7 Å 3 ) makes the series an excellent candidate to study electronic influences separately from geometric influences.…”
