The L1₁ 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.

This lattice has only rhombohedral symmetry. When the parameter "b" below is set to a the atoms are on the sites of a face centered cubic lattice.

• Prototype: CuPt
• Pearson Symbol: hR32
• Strukturbericht Designation: L1₁
• Space Group: R(-3)m (Cartesian and lattice coordinate listings available)
• Number: 166
• Other Compounds with this Structure: None
• Primitive Vectors:
  • A₁ = b X + ½ a Y + ½ a Z
  • A₂ = ½ a X + b Y + ½ a Z
  • A₃ = ½ a X + ½ a Y + b Z
• Basis Vectors:
  • B₁ = 0   (Cu)   (1a)
  • B₂ = ½ A₁ + ½ A₂ + ½ A₃ = ½ (a + b) X + ½ (a + b) Y + ½ (a + b) Z   (Pt)   (1b)

See these vectors in a better notation.
