---

• Prototype: CrNaS₂
• Strukturbericht Designation: F5₁
• Pearson Symbol: hR4
• Space Group: R3m (Cartesian and lattice coordinate listings available)
• Number: 166
• Other compounds with this structure: AgAsSe₂, HoS₂Tl, AlCV₂ Te₂TlY, many others
• Primitive Vectors:
  
  a and c are the lattice constants of the equivalent hexagonal unit cell.
  
  

  A1	=	+ ½ a X - ½ 3-½ a Y + 1/3 c Z
  A3	=	+ 3-½ a Y + 1/3 c Z
  A2	=	- ½ a X - ½ 3-½ a Y + 1/3 c Z

• Basis Vectors:

  B1	=		0		(Cr)	(1a)
  B2	=	½ (A1 + A2 + A3)	=	½ c Z	(Na)	(1b)
  B3	=	+ x (A1 + A2 + A3)	=	+ x c Z	(S)	(2c)
  B4	=	- x (A1 + A2 + A3)	=	- x c Z	(S)	(2c)
