The Cu₃S₄ V (Sulvanite, H2₄) 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)

---

• This structure is very similar to AsCu₃S₄, except that in this case the Copper atoms are on the cubic edges [the (3d) sites] rather than the cubic faces [the (3c) sites].
