2. The dihedral angle is the angle between the projections of two second-nearest-neighbor bonds on a plane perpendicular to the bond which connects them, and is 60° in the diamond cubic structure.
3. An N-member ring is a closed loop involving N nearest-neighbor bonds. In the diamond cubic structure, such rings exist only for N even and ≥ 6.
