The MoNi₄ (D1_a) 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)

---

• 6 June 2006: The primitive lattice vectors were written for a body-centered orthorhombic lattice, but the unit cell is body-centered tetragonal. The vectors used to generate the visualization are correct.
