The Fe₂C 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.

Hellner and Schwarz say that this is a derivative of the bcc structure, and who am I to argue?

• Prototype: Fe₂C
• Pearson Symbol: oP6
• Strukturbericht Designation: None
• Space Group: Pnnm (Cartesian and lattice coordinate listings available)
• Number: 58
• Primitive Vectors:
  • A₁ = a X
  • A₂ = b Y
  • A₃ = c Z
• Basis Vectors:
  • B₁ = 0 (C)
  • B₂ = ½ A₁ + ½ A₂ + ½ A₃ = ½ a X + ½ b Y + ½ c Z (C)
  • B₃ = + x A₁ + y A₂ = + x a X + y b Y (Fe)
  • B₄ = - x A₁ - y A₂ = - x a X - y b Y (Fe)
  • B₅ = + (½ + x) A₁ + (½ - y) A₂ + ½ A₃ = + (½ + x) a X + (½ - y) b Y + ½ c Z (Fe)
  • B₆ = + (½ - x) A₁ + (½ + y) A₂ + ½ A₃ = + (½ - x) a X + (½ + y) b Y + ½ c Z (Fe)

See these vectors in a better notation.
