Element C is likely to be carbon, which is known for forming various allotropes, including the molecular structure of diamond, graphite, and fullerene (C60, C70, etc.). The reference to a specific molecular structure (2) suggests a particular arrangement of atoms, which fits well with carbon's ability to form diverse allotropic structures.
