The βPu 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)

---

• This is the ``standard'' orientation of the βPu structure, as found in Pearson's Handbook. Donohue gives another orientation, as found here.

• Primitive Vectors:

  A1	=	½ a X - ½ b Y
  A2	=	½ a X - ½ b Y
