Hydrogen

Hydrogen: crystal structure

Here is some information about the crystal structure of hydrogen.

• Space group: P63/mmc (Space group number: 194)
• Structure: hcp (hexagonal close-packed).
• Cell parameters:
  • a: 470 pm
  • b: 470 pm
  • c: 340 pm
  • α: 90.000°
  • β: 90.000°
  • γ: 120.000°

You may view the structure of hydrogen:

• interactively (Jmol) or
• non-interactively

Each sphere in the picture is a molecule of hydrogen (H₂).
