which the two thiolato ligands are adjacent to each other. Since complex 3 has a more crowding aryl group on the thiolato ligands, the cis arrangement of the ligands in 3 is sterically counterintuitive and is likely due to London dispersion (LD) energy effects. Complex 4 also has an unusual structural pattern in which only a single thiolato ligand is incorporated in the structure probably for steric reasons
