The ThH₂ (L'2) 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)

---

• Prototype: ThH₂
• Pearson Symbol: tI6
• Strukturbericht Designation: L'2
• Space Group: I4/mmm (Cartesian and lattice coordinate listings available)
• Number: 139
• Other compounds with the structure: SiPt₂, TiH₂, ZrH₂
• Primitive Vectors:

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

• Basis Vectors:

  B1	=		0		(Th)	(2a)
  B2	=	+ ¼ a1 - ¼ a2 + ½ a3	=	½ a X + ¼ c Y	(H)	(4d)
  B3	=	- ¼ a1 + ¼ a2 + ½ a3	=	½ a Y + ¼ c Y	(H)	(4d)
