The title compound, bis(5-methylthio-1,2-dithiole-3-thione)-disulfide, was yielded for the first time as byproduct of the reaction of nickel(II) and cobalt(II) ions with 5-methylthio-1,2-dithiole-3-thione-4-thiolate. The compound can be obtained directly by oxidation of the ammonium salt of the ligand. C 8 H 6 S 10 forms three polymorphs: (I), which crystallizes in the orthorhombic space group P2 1 2 1 2 1 , (II) and (III), which crystallize in the monoclinic space groups P2 1 /c and P2 1 /n, respectively. The crystal and molecular structures are presented here. The determination of the absolute configuration of (I) indicated the P-helical enantiomer. In contrast to this, the crystals of (II) und (III) are racemic, containing P-and M-helical enantiomers. The polymorphs differ in the kind of skewing around the disulfide bond and of the positions of the both dithiole rings to the S-S-moiety.

Reductive dimerization of dodecylthio substituted l,Zdithiole-3-thiones 6a-b and trithion-dithiacrown ethers 1Oa-c with triethyl phosphite furnished bis-and tetrakis (dodecylthio), and bis(dithiacrown ether) substituted thiodes-aurines (E)-lla-b and (E)-l2a-c. The stereochemistry of bis(dithia[ 15]crown-5)-thiodesaurine (E)-12b has been determined by X-ray crystallographic analysis.
