Octameric puckered rings

Tjlemental sulfur belongs to group VI A of the periodic table of which oxygen, selenium, tellurium, and polonium are also members. At ambient conditions sulfur consists of octameric puckered rings (Sg) (1, 2) stacked in an orthorhombic lattice and is an insulator of high resistivity which is soluble in CS2. 

From evidence of diatomic selenium and tellurium in the vapor state and of octameric puckered rings in monoclinic selenium, as well as evidence of metallic tellurium at high pressure (23), it is suspected that in principle (if sluggish kinetics can be overcome) pressure and temperature may induce transformations in other group VI A elements comparable with those observed in sulfur.
