The BaPtSb Structure

Last modified 25 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.

• If we replace the Sb atoms by Pt the structure becomes the hexagonal omega (C32) phase.
• If we remove either the Pt or Sb atom the structure becomes the WC (B_h) phase.

• Prototype: BaPtSb
• Pearson Symbol: hP3
• Space Group: P(-6)m2 (Cartesian and lattice coordinate listings available)
• Number: 187
• Other Compounds with this Structure: AsKZn PtSbSr DyPPt GdPPt KSbZn LuPPt PPtSm PPtTB PPtTm PPtY PPtYb
• Primitive Vectors:
  • A₁ = ½ a X + ½ 3^1/2 a Y
  • A₂ = ½ a X - ½ 3^1/2 a Y
  • A₃ = c Z
• Basis Vectors:

  B1	=		0		(1a)	(Ba)
  B2	=	1/3 A1 + 2/3 A2 + 1/2 A3	=	½ a X + ½ 3½ a Y + ½ c Z	(1d)	(Pt)
  B3	=	2/3 A1 + 1/3 A2 + 1/2 A3	=	½ a X - ½ 3½ a Y + ½ c Z	(1f)	(Sb)
