Darstellung und Kristallstruktur des Bis(dicyclohexylammoniuni)-lieptasulfids [H2N(C6H11 )2]2S7/Preparation and Crystal Structure of Bis(dicyclohexylammonium )-heptasulfide [H2N(C6H11)2]2S7

The reaction of dicyclohexylamine and sulphur (molar ratio 2:7) with H2S in a mixture of dimethylformamide and formamide yields red crystals of bis(dicyclohexylammonium)heptasulfide. The compound crystallizes in the centrosymmetric space group P21,/c, the lattice constants are a = 9.787(2) Å, b = 18.972(4) Å, c = 17.118(3) Å, β = 96,12(2)°. The S72- chain has not the common helical all-trans-conformation, but a mixed conformation trans-cis-trans (sequence of the signs of torsion angles ++ - - and - - ++).
