The CuTi₃ (L6₀) 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 is a tetragonal distortion of the L1₂ (Cu₃Au) structure. The atoms are at the positions of a face centered cubic lattice when c = a. The structure is obviously related to the L1₀ (CuAu) structure, and Pearson's Handbook isn't very consistent about what is L1₀ and what is L6₀.

• Prototype: CuTi₃
• Pearson Symbol: tP4
• Strukturbericht Designation: L6₀
• Space Group: P4/mmm (Cartesian and lattice coordinate listings available)
• Number: 123
• Primitive Vectors:
  • A₁ = a X
  • A₂ = a Y
  • A₃ = c Z
• Basis Vectors:
  • B₁ = 0   (Cu)   (1a)
  • B₂ = ½ A₁ + ½ A₂ = ½ a X + ½ a Y   (Ti I)   (1c)
  • B₃ = ½ A₂ + ½ A₃ = ½ a Y + ½ c Z   (Ti II)   (2e)
  • B₄ = ½ A₁ + ½ A₃ = ½ a X + ½ c Z   (Ti II)   (2e)

See these vectors in a better notation.
