The Cuprite (C3) 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)

• Prototype: Ag₂O
• Pearson Symbol: cP6
• Strukturbericht Designation: C3
• Space Group: Pn3m (Cartesian and lattice coordinate listings available)
• Number: 224
• Other Elements with this Structure: Cu₂O, Pb₂O
• Primitive Vectors:

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

• Basis Vectors:

  B1	=		0		(Ag)	(4b)
  B2	=	½ A2 + ½ A3	=	½ a Y + ½ a Z	(Ag)	(4b)
  B3	=	½ A1 + ½ A3	=	½ a X + ½ a Z	(Ag)	(4b)
  B4	=	½ A1 + ½ A2	=	½ a X + ½ a Y	(Ag)	(4b)
  B5	=	¼ A1 + ¼ A2 + ¼ A3	=	¼ a X + ¼ a Y + ¼ a Z	(O)	(2a)
  B6	=	¾ A1 + ¾ A2 + ¾ A3	=	¾ a X + ¾ a Y + ¾ a Z	(O)	(2a)

See these vectors in LaTeX output format.
