The β-V₂N 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)

---

• Pearson's Handbook gives V₂N as the prototype, but the actual reference indicates that ε-Fe₂N is the prototype. We'll follow the Handbook here.

---

• Prototype: V₂N
• Pearson Symbol: hP9
• Strukturbericht Designation: none
• Space Group: P31m (Cartesian and lattice coordinate listings available)
• Number: 162
• Other compounds with the structure: ε-Fe₂N, Nb₂N, Ta₂N
• Reference: A. N. Christensen and B. Lebech, Acta Cryst. B 35, 2677-8 (1979).
• 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-I)	(1a)
  B2	=	+ 1/3 A1 + 2/3 A2 + ½ A3	=	+ ½ a X + 12-½ a Y + ½ c Z	(N-II)	(2d)
  B3	=	+ 1/3 A1 + 2/3 A2 + ½ A3	=	+ ½ a X + 12-½ a Y + ½ c Z	(N-II)	(2d)
  B4	=	+ x A1 + z A3	=	+ ½ x a X - ½ 3½ x a Y + z c Z	(V)	(6k)
  B5	=	+ x A2 + z A3	=	+ ½ x a X + ½ 3½ x a Y + z c Z	(V)	(6k)
  B6	=	- x A1 - x A2 + z A3	=	- x a X + z c Z	(V)	(6k)
  B7	=	- x A1 - z A3	=	- ½ x a X + ½ 3½ x a Y - z c Z	(V)	(6k)
  B8	=	- x A2 - z A3	=	- ½ x a X - ½ 3½ x a Y - z c Z	(V)	(6k)
  B9	=	+ x A1 + x A2 - z A3	=	+ x a X - z c Z	(V)	(6k)
