β-SulfurThe structure to the left marks out the unit cell with a black wireframe. These black lines are not supposed to represent chemical bonds of any sort or connect any particles, but rather to map out the volume of the repeating unit in the structure. The unit cell is in the irregularly-shaped triclinic class (see hydrated copper(II) sulfate).
