Fig. 6: Refined crystal structure of LaPt2Si2.

a Room temperature unit cell of LaPt2Si2, lanthanum atoms are represented in orange, platinum atoms in silver, silicon atoms in violet. The alternating Pt–Si planes are explicitly labeled. b Unit cell of LaPt2Si2 with the displacement ellipsoids of the respective atoms. The probability for each atom to be included in the ellipsoids was set to 100%. Beyond the aforementioned colors for the different atomic specimens, here the Pt1 atoms are represented in petrol blue and the Pt2 atoms are represented in burgundy red for clarity of display.
