WebNov 7, 2024 · Crystals Grouped by Lattices (Shape) There are seven crystal lattice systems. Cubic or Isometric: These are not always cube-shaped. You'll also find octahedrons (eight faces) and dodecahedrons (10 faces). Tetragonal: Similar to cubic crystals, but longer along one axis than the other, these crystals forming double pyramids and prisms. WebA crystalis made up of one or more atoms, called the basisor motif, at each lattice point. The basismay consist of atoms, molecules, or polymerstrings of solid matter, and the lattice provides the locations of the basis. Two Bravais lattices are often considered equivalent if they have isomorphic symmetry groups.
