• Prototype: HgS
• Pearson Symbol: hP6
• Strukturbericht Designation: B9
• Space Group: P3₂21 (Cartesian and lattice coordinate listings available)
• Number: 154
• Other Compounds with this Structure: HgO
• Primitive Vectors:

  A1	=	½ a X - ½ 3½ a Y
  A2	=	½ a X + ½ 3½ a Y
  A3	=	c Z

• Basis Vectors:

  B1	=	x1 A1 + 2/3 A3	=	x1 a/2 X - ½ 3½ x1 a Y + 2/3 c Z	(Hg)	(3a)
  B2	=	x1 A2 + 1/3 A3	=	x1 a/2 X + ½ 3½ x1 a Y + 1/3 c Z	(Hg)	(3a)
  B3	=	- x1 A1 - x1 A2	=	- x1 a X	(Hg)	(3a)
  B4	=	x2 A1 + 1/6 A3	=	x2 a/2 X - ½ 3½ x2 a Y + 1/6 c Z	(S)	(3b)
  B5	=	x2 A2 + 5/6 A3	=	x2 a/2 X + ½ 3½ x2 a Y + 5/6 c Z	(S)	(3b)
  B6	=	- x2 A1 - x2 A2 + ½ A3	=	- x2 a X + ½ c Z	(S)	(3b)
