Abstract
Abstract The aliphatic open-chain tetrathioethers, 1,2-bis(2-methylthioethylthio)ethane, 1,3-bis(2-methylthioethylthio)propane, 1,2-bis(3-methylthiopropylthio)ethane, and 1,3-bis(3-methylthiopropylthio)propane have been synthesised and reacted with divalent metal salts. They form complexes of the type [Co(ligand)I2], [Ni(ligand) X2] (X = Cl, Br, I), and [Pd2(ligand)X4] (X = Cl, Br, I), but not all ligands form each type of complex, and the donor properties of these tetrathioethers are discussed in terms of the chain lengths between the sulphur atoms. Calculation of in-plane ligand field in the trans- [Ni(ligand)X2] complexes indicates that the field strengths of the tetrathioethers changes from the solid state to solution and are also dependent on the nature of the coordinated halide.
