The Cu₃Au (L1₂) 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)

---

• All of the atoms are located on the sites of a face centered cubic lattice.

---

• Prototype: AuCu₃
• Pearson Symbol: cP4
• Strukturbericht Designation: L1₂
• Space Group: Pm3m (Cartesian and lattice coordinate listings available)
• Number: 221
• Reference: Pearson, Alloys, p. 322.
• Other Compounds with this Structure: Ni₃Al, Al₃Li (metastable), TiPt₃
• Primitive Vectors:

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

• Basis Vectors:

  B1	=		0		(Au)	(1a)
  B2	=	½ A2 + ½ A3	=	½ a Y + ½ a Z	(Cu)	(3c)
  B3	=	½ A1 + ½ A3	=	½ a X + ½ a Z	(Cu)	(3c)
  B4	=	½ A1 + ½ A2	=	½ a X + ½ a Y	(Cu)	(3c)

See these vectors in LaTeX output format.
