The αN₂ 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: αN₂
• Pearson Symbol: cP8
• Space Group: Pa3 (Cartesian and lattice coordinate listings available)
• Number: 205
• Reference: Wyckoff, Vol I, pp. 29-30
• Primitive Vectors:

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

• Basis Vectors:

  B1	=	u A1 + u A2 + u A3	=	u a X + u a Y + u a Z	(N)	(8c)
  B2	=	(½ - u) A1 - u A2 + (½ + u) A3	=	(½ - u) a X - u a Z + (½ + u) a Z	(N)	(8c)
  B3	=	-u A1 + (½ + u) A2 + (½ - u) A3	=	-u a X + (½ - u) a Y + (½ - u) a Z	(N)	(8c)
  B4	=	(½ + u) A1 + (½ - u) A2 - u A3	=	(½ + u) a X + (½ - u) a Y - u a Z	(N)	(8c)
  B5	=	-u A1 - u A2 - u A3	=	-u a X - u a Y - u a Z	(N)	(8c)
  B6	=	(½ + u) A1 + u A2 + (½ - u) A3	=	(½ + u) a X + u a Z + (½ - u) a Z	(N)	(8c)
  B7	=	u A1 + (½ - u) A2 + (½ + u) A3	=	u a X + (½ - u) a Y + (½ + u) a Z	(N)	(8c)
  B8	=	(½ - u) A1 + (½ + u) A2 + u A3	=	(½ - u) a X + (½ + u) a Y + u a Z	(N)	(8c)
