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.

• Prototype: B₆ Ca
• Pearson Symbol: cP7
• Strukturbericht Designation: D2₁
• Space Group: Pm(-3)m (Cartesian and lattice coordinate listings available)
• Number: 221
• Other systems with this Structure:
• Primitive Vectors:
  • A₁ = a X
  • A₂ = a Y
  • A₃ = a Z
• Basis Vectors:
  The Ca atoms are on the (1a) sites, the B atoms on the (6f) sites. In B₆Ca we find x = 0.207.
  • B₁ = 0 (Ca)
  • B₂ = + x A₁ + ½ A₂ + ½ A₃ = + x aX + ½ aY + ½ aZ (B)
  • B₃ = - x A₁ + ½ A₂ + ½ A₃ = - x aX + ½ aY + ½ aZ (B)
  • B₄ = + ½ A₁ + x A₂ + ½ A₃ = + ½ aX + x aY + ½ aZ (B)
  • B₅ = + ½ A₁ - x A₂ + ½ A₃ = + ½ aX - x aY + ½ aZ (B)
  • B₆ = + ½ A₁ + ½ A₂ + x A₃ = + ½ aX + ½ aY + x aZ (B)
  • B₇ = + ½ A₁ + ½ A₂ - x A₃ = + ½ aX + ½ aY - x aZ (B)
