WebThe unit cell contains four sodium ions and four chloride ions, giving the 1:1 stoichiometry required by the formula, NaCl. Figure 4. Ionic compounds with anions that are much larger than cations, such as NaCl, usually form an FCC structure. They can be described by FCC unit cells with cations in the octahedral holes. WebThe larger type of hole is found at the center of six anions (three in one layer and three in an adjacent layer) located at the corners of an octahedron; this is called an octahedral hole. Figure 39.21 illustrates both of these types of holes. Figure 39.22. Cations may occupy two types of holes between anions: octahedral holes or tetrahedral holes. phillip sternsWebThe tetrahedral holes are the small lightly colored circles at the corners of the inner cube.
