# The CoU (Ba) Structure

You can now

• When xCo = ¼ and xU = 0, or visa versa, this structure reduces to CsCl (B2) with aB2 = ½ a.

• Prototype: CoU
• Pearson Symbol: cI16
• Strukturbericht Designation: Ba
• Space Group: I213 (Cartesian and lattice coordinate listings available)
• Number: 199
• Other Compounds with this Structure: Ga2Pu3
• Primitive Vectors:  A1 = -½ a X + ½ a Y + ½ a Z A2 = + ½ a X - ½ a Y + ½ a Z A3 = + ½ a X + ½ a Y - ½ a Z
• Basis Vector:  B1 = + 2 xCo A1 + 2 xCo A2 + 2 xCo A3 = + xCo a X + xCo a Y + xCo a Z (Co) (8a) B2 = + ½ A1 + (½ -2 xCo) A3 = - xCo a X + (½ - xCo) a Y + xCo a Z (Co) (8a) B3 = + (½ -2 xCo) A2 + ½ A3 = + (½ - xCo) a X + xCo a Y - xCo a Z (Co) (8a) B4 = + (½ -2 xCo) A1 + ½ A2 = + xCo a X - xCo a Y + (½ - xCo) a Z (Co) (8a) B5 = + 2 xU A1 + 2 xU A2 + 2 xU A3 = + xU a X + xU a Y + xU a Z (U) (8a) B6 = + ½ A1 + (½ -2 xU) A3 = - xU a X + (½ - xU) a Y + xU a Z (U) (8a) B7 = + (½ -2 xU) A2 + ½ A3 = + (½ - xU) a X + xU a Y - xU a Z (U) (8a) B8 = + (½ -2 xU) A1 + ½ A2 = + xU a X - xU a Y + (½ - xU) a Z (U) (8a)
