The B26 (CuO, Tenorite) 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.

• Prototype: CuO
• Pearson Symbol: mC8
• Strukturbericht Designation: B26
• Space Group: C2/c (Cartesian and lattice coordinate listings available)
• Number: 15
• Other compounds with this structure: AgO

  When a=b=c and ß = 90° the Copper atoms are on the sites of an fcc lattice.
  
  

• Primitive Vectors:
  • A₁ = ½ a X - ½ b Y
  • A₂ = ½ a X + ½ b Y
  • A₃ = c cos(ß) X + c sin(ß) Z
• Basis Vectors:
  • B₁ = ½ A₂ = ¼ a X + ¼ b Y   (Cu)   (4c)
  • B₂ = ½ A₁ + ½ A₃ = [¼ a + ½ c cos(ß)] X - ¼ b Y + ½ c sin(ß) Z   (Cu)   (4c)
  • B₃ = - y A₁ + y A₂ + ¼ A₃ = + ¼ c cos(ß) X + y b Y + ¼ c sin(ß) Z   (O)   (4f)
  • B₄ = + y A₁ - y A₂ - ¼ A₃ = - ¼ c cos(ß) X - y b Y - ¼ c sin(ß) Z   (O)   (4f)

See these vectors in a better notation.
