The CrB (B33) 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)

---

• Note that removing either the Cr or B atoms transforms this into the alpha-Uranium (A20) structure.
• 15 Jun 2006: Corrected the lattice coordinates of the basis vectors. The previous coordinates were for the alternate set of primitive vectors found on the LaTeX output page. The atomic coordinates used to draw the pictures are unchanged but we did add type primitive and basis vectors to the download file.

• Primitive Vectors:

  A1	=	½ a X - ½ b Y
  A2	=	½ a X + ½ b Y
  A3	=	c Z

• Basis Vectors:

  B1	=	- x1 A1 + x1 A2 + ¼ A3	=	+ x1 b Y + ¼ c Z	(4c)	(Cr)
  B2	=	+ x1 A1 - x1 A2 + ¾ A3	=	- x1 b Y + ¾ c Z	(4c)	(Cr)
  B3	=	- x2 A1 + x2 A2 + ¼ A3	=	+ x2 b Y + ¼ c Z	(4c)	(B)
  B4	=	+ x2 A1 - x2 A2 + ¾ A3	=	- x2 b Y + ¾ c Z	(4c)	(B)

See the positions in LaTeX output format with alternative primitive vectors.
