The γN₂ 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)

---

• Prototype: N₂ (γ)
• Pearson Symbol: tP4
• Space Group: P4₂/mnm (Cartesian and lattice coordinate listings available)
• Number: 136
• Reference: Donohue, pp. 287-9.
• Primitive Vectors:

  A1	=	a X
  A2	=	a Y
  A3	=	c Z

• Basis Vectors:

  B1	=	+ u A1 + u A2	=	+ a u X + a u Y	(N)	(4f)
  B2	=	- u A1 - u A2	=	- a u X - a u Y	(N)	(4f)
  B3	=	(½ + u) A1 + (½ - u) A2 + ½ A3	=	(½ + u) a X + (½ - u) a Y +½ c Z	(N)	(4f)
  B4	=	(½ - u) A1 + (½ + u) A2 + ½ A3	=	(½ - u) a X + (½ + u) a Y +½ c Z	(N)	(4f)
