# The αN2 Structure

You can now

• 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)
