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.

See the completely different B16 (GeS) structure.

• Prototype: FeB
• Pearson Symbol: oP8
• Strukturbericht Designation: B27
• Space Group: Pnma (Cartesian and lattice coordinate listings available)
• Number: 62
• Primitive Vectors:
  • A₁ = a X
  • A₂ = b Y
  • A₃ = c Z
• Basis Vectors:
  • B₁ = + x₁A₁ + ¼ A₂ + z₁A₃ = + x₁ aX + ¼ bY + z₁ cZ (Fe)
  • B₂ = - x₁A₁ - ¼ A₂ - z₁A₃ = - x₁ aX - ¼ bY - z₁ cZ (Fe)
  • B₃ = (½ - x₁) A₁ - ¼ A₂ + (½ + z₁)A₃ = + (½ - x₁) aX - ¼ bY + (½ + z₁) cZ (Fe)
  • B₄ = (½ + x₁) A₁ + ¼ A₂ + (½ - z₁)A₃ = + (½ + x₁) aX + ¼ bY + (½ - z₁) cZ (Fe)
  • B₅ = + x₂A₁ + ¼ A₂ + z₂A₃ = + x₂ aX + ¼ bY + z₂ cZ (B)
  • B₆ = - x₂A₁ - ¼ A₂ - z₂A₃ = - x₂ aX - ¼ bY - z₂ cZ (B)
  • B₇ = (½ - x₂) A₁ - ¼ A₂ + (½ + z₂)A₃ = + (½ - x₂) aX - ¼ bY + (½ + z₂) cZ (B)
  • B₈ = (½ + x₂) A₁ + ¼ A₂ + (½ - z₂)A₃ = + (½ + x₂) aX + ¼ bY + (½ - z₂) cZ (B)

See these vectors in a better notation.
