The monoclinic Phosphorus 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)

---

• The unit cell of monoclinic Phosphorus consists of 21 sets of atoms sitting at the (4g) (and general) sites of space group P2/c. We'll only list the coordinates for a generic set of atoms.
• The pictures on this page show only the atoms in one unit cell of the structure. This is enough to show the parallel tubes of double layers.

• Prototype: P
• Pearson Symbol: mP84
• Space Group: P2/c (Cartesian and lattice coordinate listings available)
• Number: 13
• Reference: Donohue, pp. 292-5.
• Primitive Vectors:

  A1	=	a X
  A2	=	b Y
  A3	=	c cos(β) X + c sin(β) Z

• Basis Vectors:

  For j = 1, 2, 3, ... , 21:

  B4j-3	=	+ xj A1 + yj A2 + zj A3	=	+ [xj a + zj c cos(β)] X + yj b Y + zj c sin(β) Z	(P-j)	(4g)
  B4j-2	=	- xj A1 + yj A2 + (½ - zj) A3	=	- [xj a - (½ - zj) c cos(β) X + yj b Y + (½ - zj) c sin(β) Z	(P-j)	(4g)
  B4j-1	=	- xj A1 - yj A2 - zj A3	=	- [xj a + zj c cos(β)] X - yj b Y - zj c sin(β) Z	(P-j)	(4g)
  B4j	=	+ xj A1 - yj A2 + (½ + zj) A3	=	+ [xj a + (½ + zj) c cos(β) X - yj b Y + (½ + zj) c sin(β) Z	(P-j)	(4g)
