Crystal structure of boron carbide

Figure 5: The crystal structure of B₁₃C₂ ("B₄C") in the hexagonal setting. All boron atoms symbolized by filled circles form (empty) icosahedra. Other boron atoms (open circles) are located in the centers of linear C-B-C units. At the left-hand side the stackings (ABC) of this rhombohedral structure are indicated.
