The Au₅Mn₂ Structure

You can now

• see the structure from several perspectives;
• examine the structure with an external viewer; or
• download the coordinates of the atoms in these pictures in XYZ format.
• visualize the structure (Uses the JMOL Applet)

---

• As noted by Pearson, this structure is cubic close-packed. As such, it is frequently used for cluster expansion models.
