The B10 (Lead Oxide) 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.

• When z = ½ the atoms in this structure are in the L1₀ (CuAu) structure.
• Pearson places one of the Oxygen atoms at the origin. We prefer the alternative choice, where the origin is at an inversion site.
• This structure is identical to the beta-Np (A_d) structure.
  • Prototype: PbO
  • Pearson Symbol: tP4
  • Strukturbericht Designation: B10
  • Space Group: P4/nmm (Cartesian and lattice coordinate listings available)
  • Number: 129
  • Other Compounds with this Structure: BiIn, FeSe, FeS, OSn, CuFeTe₂, beta-Np
  • Primitive Vectors:
    • A₁ = a X
    • A₂ = a Y
    • A₃ = c Z
  • Basis Vectors:

    B1	=	¾ A1 + ¼ A2	=	¾ a X + ¼ a Y	(O)	(2a)
    B2	=	¼ A1 + ¾ A2	=	¼ a X + ¾ a Y	(O)	(2a)
    B3	=	¼ A1 + ¼ A2 + z A3	=	¼ a X + ¼ a Y + z c Z	(Pb)	(2c)
    B4	=	¾ A1 + ¾ A2 + z A3	=	¾ a X + ¾ a Y - z c Z	(Pb)	(2c)
