The BaS₃ 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)

---

• Not to be confused with the other BaS₃ (D0₁₇) structure, which has space group P42₁m (#113).
• The experimentally determined coordinates list
  z₁ = 0.00
  z₂ = 0.00
  x₃ = 0.25
  y₃ = 0.25
  z₃ = 0.00
  x₄ = 0.25
  y₄ = 0.50
  z₄ = 0.00 ,
  but other values are allowed. To illustrate this, the coordinate file has coordinates slightly offset from the values above.
