It consists of a unit cell structure called a dodecahedron consists of 60-70 Carbon atoms in the unit cell. It has potential as a super conductor Other Polymorphic Solids Calcium Carbonate has two unit cell structures which are exhibited in the form of chalk and marble. They look so much different, but they are composed of the same Calcium Carbonate. Orthorombic Monoclinic Triclinic Amorphic Solids Amorphic solids have no crystal unit cell structure. The particles are haphazardly arraigned.
Sulfur has an amorphic form.
It is interesting that when molten sulfur is poured into a beaker of room temperature water, the sulfur solidifies as an amorphous form of Sulfur that has the consistency of sticky rubber bands. However, when you place a sample of the amorphous sulfur on a watch glass and leave it for several days, you will observe crystalline sulfur reappearing. Apparently, given enough time the Sulfur atoms can migrate to positions in a crystal lattice.
