The complexes (1), (3), and 2> (5) have been synthesised by the reactions of K2 or with the respective polythiol in the presence of triethylamine in methanol solution.Complex (1) crystallises in space group Pcab with a=15.122(3), b=18.685(4), c=19.648(4) Angstroem, U=5542.02 Angstroem3, and Z=4.Structure solution based on 2072 independent reflections was refined to R=0.063.Complex (3) crystallises in space group P21/c with a=9.539(3), b=15.123(4), c=21.815(4) Angstroem, β=93.58(1) deg, U=3140.9 Angstroem3, and Z=8.Structure solution based on 3329 independent reflections was refined to R=0.029.Complex (5) crystallises in space group P21/n with a=11.506(3), b=17.096(4), c=18.115(4) Angstroem, β=102.32(1) deg, U=3488.9 Angstroem3, and Z=4.Structure solution based on 2380 independent reflections was refined to R=0.0517.The - and - anions exhibit square pyramidal geometry with a terminal sulphido or oxo ligand in the apical position.The S2- ligand is derived from decomposition of the 1,2-ethanedithiolate anion with elimination of ethylene.The 2>- anion has a six-co-ordinate Re atom in a trigonal prismatic co-ordination sphere.The factors responsible for the adoption of the trigonal prismatic structure are discussed.
