Single-Crystal Structures of Benzenehexathiol and Its Disulfide Forms.

Oligothiols are useful as building blocks in the construction of disulfide-based macrocycles and polymers or as ligands for coordination polymers. Above all, benzenehexathiol () is a particularly important molecule, as it is used to construct conductive two-dimensional MOFs. Despite the desire to clarify its structure and isolate it to high purity, the chemical instability of has hampered single-crystal X-ray structure analysis of intact .
