Abstract
(PPN)2C16S18 was obtained by the addition of PPN+Cl- to a methanolic extract of Na2C4Sx, derived from the reaction of C6S8O2 and NaOMe. Centrosymmetric C16S184- consists of thiophene units unsymmetrically fused to two 1,4-dithiin rings. Solutions of C16S184- convert to C8S82- with heating. When C4Sx (x ∼ 8) is reduced by Na/NH3 followed by extraction and crystallization, one obtains the bicyclic polysulfide C4S82-, crystallized as its PPh4+ salt.
