# The CuS (B18) Structure

You can now

• Prototype: CuS
• Pearson Symbol: hP12
• Space Group: P63/mmc (Cartesian and lattice coordinate listings available)
• Number: 194
• Other compounds with this structure: CuSe
• 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 = 1/3 A1 + 2/3 A2 + ¼ A3 = ½ a X + 12-½ a Y + ¼ c Z (2c) (S-I) B2 = 2/3 A1 + 1/3 A2 + ¾ A3 = ½ a X - 12-½ a Y + ¾ c Z (2c) (S-I) B3 = 2/3 A1 + 1/3 A2 + ¼ A3 = ½ a X - 12-½ a Y + ¼ c Z (2d) (Cu-I) B4 = 1/3 A1 + 2/3 A2 + ¾ A3 = ½ a X + 12-½ a Y + ¾ c Z (2d) (Cu-I) B5 = + z1 A3 = + z1 c Z (4e) (S-II) B6 = - z1 A3 = - z1 c Z (4e) (S-II) B7 = (½ + z1) A3 = (½ + z1) c Z (4e) (S-II) B8 = (½ - z1) A3 = (½ - z1) c Z (4e) (S-II) B9 = 1/3 A1 + 2/3 A2 + z2 A3 = ½ a X + 12-½ a Y + z2 c Z (2c) (S-I) B10 = 2/3 A1 + 1/3 A2 - z2 A3 = ½ a X - 12-½ a Y - z2 c Z (2c) (S-I) B11 = 2/3 A1 + 1/3 A2 + (½ + z2) A3 = ½ a X - 12-½ a Y + (½ + z2) c Z (2d) (Cu-I) B12 = 1/3 A1 + 2/3 A2 + (½ - z2) A3 = ½ a X + 12-½ a Y + (½ - z2) c Z (2d) (Cu-I)
