The PdSn₂ (C_e) 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)

---

• Removing the second set of Pd atoms changes this to the D1_c structure.

• Basis Vectors:

  B1	=	- z1 A2 + z1 A3	=	+ z1 c Z	(Pd-I)	(4a)
  B2	=	+ ½ A2 + (½ - z1) A2 + (½ + z1) A3	=	+ ½ a X + ½ b Y + z1 c Z	(Pd-I)	(4a)
  B3	=	- z2 A2 + z2 A3	=	+ z2 c Z	(Pd-II)	(4a)
  B4	=	+ ½ A2 + (½ - z2) A2 + (½ + z2) A3	=	+ ½ a X + ½ b Y + z2 c Z	(Pd-II)	(4a)
  B5	=	+ x3 A1 + (y3 - z3) A2 + (y3 + z3) A3	=	+ x3 a X + y3 b Y + z3 c Z	(Sn-I)	(8b)
  B6	=	- x3 A1 - (y3 + z3) A2 - (y3 - z3) A3	=	- x3 a X - y3 b Y + z3 c Z	(Sn-I)	(8b)
  B7	=	+ (x3 - ½) A1 + (½ - y3 - z3) A2 + (½ - y3 + z3) A3	=	+ (x3 - ½) a X + (y3 + ½) b Y + z3 c Z	(Sn-I)	(8b)
  B8	=	+ (½ - x3) A1 + (y3 - z3 - ½) A2 + (y3 + z3 + ½) A3	=	+ (½ - x3) a X + (y3 - ½) b Y + z3 c Z	(Sn-I)	(8b)
  B9	=	+ x4 A1 + (y4 - z4) A2 + (y4 + z4) A3	=	+ x4 a X + y4 b Y + z4 c Z	(Sn-II)	(8b)
  B10	=	- x4 A1 - (y4 + z4) A2 - (y4 - z4) A3	=	- x4 a X - y4 b Y + z4 c Z	(Sn-II)	(8b)
