But that's not all! The icosahedra are connected by struts! These struts have carbon atoms at their ends and a boron in the middle. Only one strut is shown in detail here. The carbon atoms are the black balls and the boron is the little green ball. Overall there are 4 boron atoms per carbon atom, so people call boron carbide B 4 C.
