What is the shape of NaCl​

Answer»

NaCl has a cubic unit cell. It is best thought of as a face-centered cubic array of anions with an interpenetrating FCC cation lattice (or vice-versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6-coordinate and has a local octahedral geometry.

  • Lattice Type: Face-Centered
  • Cystal System: Cubic
  • Cell PARAMETERS: a = 5.6402 Å, Z=4
  • Alternate NAMES: Halite, rock SALT, sea salt, table salt, salt
