The Fe₄C Structure

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.
• visualize the structure (Uses the JMOL Applet)

---

• When x = ¼, the iron atoms are at the positions of the face centered cubic lattice. In Fe₄C, x is about 0.265.

• Prototype: Fe₄C
• Pearson Symbol: cP5
• Space Group: P43m (Cartesian and lattice coordinate listings available)
• Number: 215
• Reference: Villars and Calvert, Pearson's Handbook Vol. II, p. 1895.
• Primitive Vectors:

  A1	=	a X
  A2	=	a Y
  A3	=	a Z

• Basis Vectors:

  B1	=		0		(1a)	(C)
  B2	=	+ x A1 + x A2 + x A3	=	+ x a X + x a Y + x a Z	(4e)	(Fe)
  B3	=	+ x A1 - x A2 - x A3	=	+ x a X - x a Y - x a Z	(4e)	(Fe)
  B4	=	- x A1 + x A2 - x A3	=	- x a X + x a Y - x a Z	(4e)	(Fe)
  B5	=	- x A1 - x A2 + x A3	=	- x a X - x a Y + x a Z	(4e)	(Fe)

See these vectors LaTeX output format.
