The Cuprite (C3) Structure

Last modified 5 October 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.

• Prototype: Ag₂O
• Pearson Symbol: cP6
• Strukturbericht Designation: C3
• Space Group: Pn(-3)m (Cartesian and lattice coordinate listings available)
• Number: 224
• Other Elements with this Structure: Cu₂O, Pb₂O
• Primitive Vectors:
  • A₁ = a X
  • A₂ = a Y
  • A₃ = a Z
• Basis Vector:
  • B₁ = 0   (Ag)
  • B₂ = ½ A₂ + ½ A₃ = ½ a Y + ½ a Z   (Ag)
  • B₃ = ½ A₁ + ½ A₃ = ½ a X + ½ a Z   (Ag)
  • B₄ = ½ A₁ + ½ A₂ = ½ a X + ½ a Y   (Ag)
  • B₅ = ¼ A₁ + ¼ A₂ + ¼ A₃ = ¼ a X + ¼ a Y + ¼ a Z   (O)
  • B₆ = ¾ A₁ + ¾ A₂ + ¾ A₃ = ¾ a X + ¾ a Y + ¾ a Z   (O)

See these vectors in a better notation.
