Weak complexes of sulphur and selenium. Part II. Complex species of SO2, SOCl2, and SO2Cl2 with the thiocyanate ligand
Abstract
The formation of 1 : 1 complex species between SO2, SOCl2, and SO2Cl2 with the SCN– ligand is reported in dilute solutions. Their thermodynamic constants point to a weak association of a charge-transfer type. The nature of the complex species is discussed in relation to polarisability and basicity of the SCN– ligand.
