Abstract: | The synthesis and structural characterization of bis(2-(1,3,2-benzodithiarsol-2ylsulfanyl)-benzenesulfide) (1) and 2-chloro-benzo-1,3,2-dithiastibole (2) are reported. Both compounds contain a five-membered ring with sulfur bound to the central group 15 atom. In compound 1, the centroidal distance between each opposing arene is 3.819 Å. An alternating arene sandwich structure is created in the solid state with an intramolecular centroid distance between each set of stacked rings of 5.467 Å. Compound 2 is an example of a three coordinate antimony dithiolate. It does not possess any of the secondary interactions seen in 1. Compound 2 demonstrates trigonal bypyramidal geometry around the antimony if secondary interactions are considered. |
