The Li₃N Crystal 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)

---

• Removing the Nitrogen atom makes this structure equivalent to hexagonal ω (AlB₂).

---

• Prototype: Li₃N
• Pearson Symbol: hP4
• Space Group: P6/mmm (Cartesian and lattice coordinate listings available)
• Number: 191
• Reference: Pearson, Alloys, p 503.
• Primitive Vectors:

  A1	=	½ a X - ½ 31/2 a Y
  A2	=	½ a X + ½ 31/2 a Y
  A3	=	c Z

• Basis Vectors:

  B1	=		0		(N)	(1a)
  B2	=	+ ½ A3	=	+ ½ c Z	(Li-I)	(1b)
  B3	=	1/3 A1 + 2/3 A2	=	½ a X + 12-½ a Y	(Li-II)	(2c)
  B4	=	2/3 A1 + 1/3 A2	=	½ a X - 12-½ a Y	(Li-II)	(2c)
