The αPu 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)

---

• We've corrected the corrected the Y components to reflect the fact that a ≠ b

---

• Prototype: αPu
• Pearson Symbol: mP16
• Space Group: P2₁/m (Cartesian and lattice coordinate listings available)
• Number: 11
• Primitive Vectors:

  A1	=	a X
  A2	=	b Y
  A3	=	c cos(β) X + c sin(β) Z

• Basis Vectors:
  
  The atoms sit on 8 pairs of (2e) sites. Rather than list them all, we'll list only one pair:
  
  

  B2i-1	=	+ xi A1 + ¼ A2 + zi A3	=	+ [xi a + zi c cos(β)] X + ¼ b Y + zi c sin(β) Z	(Pu-i)	(2e)
  B2i	=	- xi A1 + ¾ A2 - zi A3	=	- [xi a + zi c cos(β)] X + ¾ b Y - zi c sin(β) Z	(Pu-i)	(2e)
