cis-Dichlorido(3,6,9-trithiabicyclo[9.3.1]pentadecane-κ2S3,S6)palladium(II) acetonitrile 0.8-solvate.

In the title complex, [PdCl2(C12H22S3)]·0.8CH3CN, a potentially tridentate thioether ligand coordinates in a cis-bidentate manner to yield a square-planar environment for the PdII cation [mean deviation of the Pd from the Cl2S2 plane = 0.0406 (7) A]. Each square-planar entity packs in an inverse face-to-face manner, giving pairs with plane-to-plane separations of 3.6225 (12) A off-set by 1.1263 (19) A, with a PdPd separation of 3.8551 (8) A. A partial acetonitrile solvent molecule is present. The occupancy of this molecule was allowed to refine, and converged to 0.794 (10). The synthesis of the previously unreported 3,6,9-trithiabicyclo[9.3.1]pentadecane ligand is also outlined.
