Abstract: | Abstract Hexathia-18-crown-6 (18-S-6) exhibits a cyclic structure with all the heteroatoms being directed out of the macrocyclic ring (exodentate conformation). In a previous report on a different crystalline modification of this compound, the crown contains two C-S linkages which are anti, rather than all such linkages being gauche. The title compound crystallizes in the monoclinic space group P21/c with a = 5.833(1), b = 11.148(1), c = 13.191(1) Å, β = 93.29(1)°, and Dc = 1.404 g cm?3 for Z = 2. Refinement based on 983 observed reflections led to R = 0.058. |
