1. Crystal structure of Diamond Diamond structure is like a face-centered cubic(FCC) lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons. A tetrahedron has four faces and six edges. It is like an Egyptian pyramid in which the base is a triangle instead of a square.

2. Diamond structure Imagine a face-centered cubic lattice! Diamond is composed of pure carbon.

3. Diamond structure view the cube from a green arrow along the diagonal a diagonal passing through the center of a cube

4. 1 3 2 1 2 3 Diamond structure This is the cubic lattice viewed from a green arrow. In a diamond structure, a carbon exists at the center of a regular tetrahedron consisted of a and three .
