The NaTl (B32) 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)

---

• Both sublattices form independent diamond structures.
• The atoms sit on the sites of a bcc lattice with a_bcc = ½ a.
• Corrected names of Wyckoff positions
• 17 Feb 2007: Corrected numbering on basis vectors

• Prototype: NaTl
• Pearson Symbol: cF16
• Strukturbericht Designation: B32
• Space Group: Fd3m (Cartesian and lattice coordinate listings available)
• Number: 227
• Reference: Pearson (Alloys), p. 576.
• Primitive Vectors:

  A1	=	½ a Y + ½ a Z
  A2	=	½ a X + ½ a Z
  A3	=	½ a X + ½ a Y

• Basis Vectors:

  B1	=	+ 1/8 A1 + 1/8 A2 + 1/8 A3	=	+ 1/8 a X + 1/8 a Y + 1/8 a Z	(Na)	(8a)
  B2	=	- 1/8 A1 - 1/8 A2 - 1/8 A3	=	- 1/8 a X - 1/8 a Y - 1/8 a Z	(Na)	(8a)
  B3	=	+ 3/8 A1 + 3/8 A2 + 3/8 A3	=	+ 3/8 a X + 3/8 a Y + 3/8 a Z	(Tl)	(8b)
  B4	=	- 3/8 A1 - 3/8 A2 - 3/8 A3	=	- 3/8 a X - 3/8 a Y - 3/8 a Z	(Tl)	(8b)
