The Cu₂Mg Cubic Laves Structure (C15)

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)

---

• The Mg atoms are located on the sites of the diamond structure. The stacking of the Mg dimers is ABCABC.

• Prototype: Cu₂Mg
• Pearson Symbol: cF24
• Strukturbericht Designation: C15
• Space Group: Fd3m (Cartesian and lattice coordinate listings available)
• Number: 227
• Reference: Wyckoff, Vol. I, pp. 365-367.
• Other Compounds with this Structure: CsBi₂, RbBi₂
• Primitive Vectors:

  A1	=	½ a Y + ½ a Z
  A2	=	½ a X + ½ a Z
  A3	=	½ a X + ½ a Y

• Basis Vectors:

  B1	=	1/8 A1 + 1/8 A2 + 1/8 A3	=	1/8 a X + 1/8 a Y + 1/8 a Z	(Mg)	(8a)
  B2	=	7/8 A1 + 7/8 A2 + 7/8 A3	=	7/8 a X + 7/8 a Y + 7/8 a Z	(Mg)	(8a)
  B3	=	½ A1 + ½ A2 + ½ A3	=	½ a X + ½ a Y + ½ a Z	(Cu)	(16d)
  B4	=	½ A2 + ½ A3	=	½ a X + ¼ a Y + ¼ a Z	(Cu)	(16d)
  B5	=	½ A1 + ½ A3	=	¼ a X + ½ a Y + ¼ a Z	(Cu)	(16d)
  B6	=	½ A1 + ½ A2	=	¼ a X + ¼ a Y + ½ a Z	(Cu)	(16d)

See these vectors in LaTex output format.
