The PbO (B10) 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)

---

• 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.
• 22 Jan 2009: Fixed sign of the B₄ lattice coordinates.

• 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)
