The Ga₃Pt₅ 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)

---

• When a = b = 2 c and x₁ = x₂ = ¼ the atoms are on the sites of a face centered cubic lattice. The data for Al₃Ni₅ in Pearson's Handbook show that this compound is very close to the ideal structure.
• Pearson doesn't provide atomic coordinates for the prototype structure, Ga₃Pt₅, so we use the data for Al₃Ni₅ in the same structure.

• Prototype: Ga₃Pt₅
• Pearson Symbol: oC16
• Space Group: Cmmm (Cartesian and lattice coordinate listings available)
• Number: 65
• Other compounds with this structure: Al₃Ni₅, Ga₃Ni₅, Ni₃Pd₅
• Primitive Vectors:

  A1	=	½ a X - ½ b Y
  A2	=	½ a X + ½ b Y
  A3	=	c Z

• Basis Vectors:

  B1	=		0		(Ni-I)	(2a)
  B2	=	½ A2	=	¼ a X + ¼ b Y	(Ni-II)	(4e)
  B3	=	½ A1	=	¼ a X - ¼ b Y	(Ni-II)	(4e)
  B4	=	- x1 A1 + x1 A2 + ½ A3	=	+ x1 b Y + ½ c Z	(Ni-III)	(4j)
  B5	=	+ x1 A1 - x1 A2 + ½ A3	=	- x1 b Y + ½ c Z	(Ni-III)	(4j)
  B6	=	½ A1 + ½ A2	=	½ a X	(Al-I)	(2b)
  B7	=	+ x2 A1 + x2 A2 + ½ A3	=	+ x2 a X + ½ c Z	(Al-II)	(4h)
  B8	=	- x2 A1 - x2 A2 + ½ A3	=	- x2 a X + ½ c Z	(Al-II)	(4h)
