Learn about the rock-salt structure of NaCl, also known as halite or sodium chloride, with this interactive 3D model. Explore the coordination, polyhedra, and relation to fcc structure of this ionic compound.
Halite (/ ˈ h æ l aɪ t, ˈ h eɪ l aɪ t / HAL-yte, HAY-lyte), [7] [8] [9] commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl). Halite forms isometric crystals . [ 10 ]
This same basic structure is found in many other compounds and is commonly known as the NaCl structure or rock salt crystal structure. It can be represented as a face-centered cubic (fcc) lattice with a two-atom basis or as two interpenetrating face centered cubic lattices.
2 gru 2020 · 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.
9 wrz 2023 · Halite, or rock salt, is a cubic mineral composed of sodium and chlorine ions. It forms in various geological settings, such as marine evaporites, inland saline lakes, salt flats, and salt domes, and has many applications in industry and life.
Sodium Chloride, also known as Rock salt structure, adopts a face centred cubic (fcc) lattice with a two-atom basis. This can be also represented as two separate fcc arrays for the negatively charged anions (e.g. Cl-) and the positively charged cations (e.g. Na+), which are separated by ½ of the body diagonal of the cubic unit cell.
