# The GeS (B16) Structure

You can now

• Pearson says that this structure is a distorted NaCl (B1) structure. So far I haven't found the magic values of the parameters that makes this so.
• You may be wondering what the difference is between this structure and the B27 (FeB) structure. You are entitled.
• This structure was suggested for inclusion by Dr. Soon-Ku Hong of Samsung.
• Thanks to Dr. Sang Yang for pointing out some notational errors in the lattice coordinates of the basis vectors.

• Prototype: GeS
• Pearson Symbol: oP8
• Strukturbericht Designation: B16
• Space Group: Pnma (Cartesian and lattice coordinate listings available)
• Number: 62
• Other Compounds with this Structure: GeSe, GeS, GeTe, PbS, PBSe, PbTe, SnS, SnSe, SnTe
• Primitive Vectors:  A1 = a X A2 = b Y A3 = c Z
• Basis Vector:  B1 = + x1 A1 + ¼ A2 + z1 A3 = + x1 a X + ¼ b Y + z1 c Z (Ge) (4c) B2 = - x1 A1 + ¾ A2 - z1 A3 = - x1 a X + ¾ b Y - z1 c Z (Ge) (4c) B3 = (½ - x1) A1 + ¾ A2 + (½ + z1) A3 = (½ - x1) a X + ¾ b Y + (½ + z1) c Z (Ge) (4c) B4 = (½ + x1) A1 + ¼ A2 + (½ - z1) A3 = (½ + x1) a X + ¼ b Y + (½ - z1) c Z (Ge) (4c) B5 = + x2 A1 + ¼ A2 + z2 A3 = + x2 a X + ¼ b Y + z2 c Z (S) (4c) B6 = - x2 A1 + ¾ A2 - z2 A3 = - x2 a X + ¾ b Y - z2 c Z (S) (4c) B7 = (½ - x2) A1 + ¾ A2 + (½ + z2) A3 = (½ - x2) a X + ¾ b Y + (½ + z2) c Z (S) (4c) B8 = (½ + x2) A1 + ¼ A2 + (½ - z2) A3 = (½ + x2) a X + ¼ b Y + (½ - z2) c Z (S) (4c)
