3,5-Bis(trimethylsilyl)triphenyleno[1,12-bcd]thiophene

In the title compound, C24H26SSi2, the fused ring system plus the two Si atoms are coplanar, consistent with planar triphenyl-ene but contrary to bowl-shaped triphenyl-eno[1,12-bcd:4,5-b′c′d′:8,9- b′′c′′d′′]trithio-phene. The bond alternation pattern of the C - C bonds in the title compound is similar to that found in triphenyl-eno[1,12-bcd:4,5-b′c′d′:8,9- b′′c′′d′′]trithio-phene, although the lengths of the C - C bonds around the central and thio-phene rings of the title compound are slightly different from the corresponding bonds of triphenyl-eno[1,12-bcd:4,5-b′c′d′:8,9- b′′c′′d′′]trithio-phene.
