Thiabowls: synthesis, molecular structure and the solid state architecture of tetrathia-[4]-peristylane

[摘要] Synthesis of tetrathia-[4]-peristylane, the first thiabowl, from the dimer of cyclooctatetraene has been accomplished. The X-ray crystal structure of the tetrathiabowl indicates significant departure from the expected C-4v symmetry and in the solid state it exhibits a multi-columnar arrangement and a novel 'self-inclusion' phenomenon, directed by a network of S...S and CH...S interactions.
