The AlFe₃ (D0₃) Structure

Last modified 5 April 2001

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.

Notes:

• The structure is crystallographically equivalent to the L2₁ (Heusler) strcture.
• The atoms sit on the sites of a body centered cubic lattice.

• Prototype: AlFe₃
• Pearson Symbol: cF16
• Strukturbericht Designation: D0₃
• Space Group: Fm(-3)m (Cartesian and lattice coordinate listings available)
• Number: 225^*
• Other Compounds with this Structure: BiFe₃
• Primitive Vectors:
  • A₁ = a Y + a Z
  • A₂ = a X + a Z
  • A₃ = a X + a Y
• Basis Vector:
  • B₁ = 0   (Al)   (4a)
  • B₂ = - ½ A₁ + ½ A₂ + ½ A₃ = a X   (Fe)   (4b)
  • B₃ = + ¼ A₁ + ¼ A₂ + ¼ A₃ = + ½ a X + ½ a Y + ½ a Z   (Fe)   (8c)
  • B₄ = - ¼ A₁ - ¼ A₂ - ¼ A₃ = - ½ a X - ½ a Y - ½ a Z   (Fe)   (8c)

See these vectors in a better notation.
