Dispiro[fluorene-9,5′-[1,2,3,4]tetrathiane-6′,9′′-fluorene] [PDF]
Acta Crystallographica Section C Crystal Structure Communications, 2001 The tetrathiane ring of the title compound, C26H16S4, has a chair conformation and the molecule has approximate C2 symmetry. Each of the two fluorene ring systems is virtually planar, with the ring planes intersecting at an angle of 67.58 (5)°. This novel compound has been formed as a side product from the treatment of 9H-fluorene-9-thione with methyl ...
