Abstract
Abstract Some reactions between palladium compounds and 3-thiomorpholinone (T) were examined, the compounds PdCl 2 T 2 and PdBr 2 T 2 being isolated in solid state. The reaction between PdBr 4 2− and T is quantitative and may be followed by means of conductometric or high-frequency titrations; the compound PdCl 2 T 2 is fairly soluble in water and hydrolises to form the compound Pd(OH) 2 T 2 . Spectrophotometric study of the system formed from PdCl 4 2− and T reveals that the compound PdCl 2 T 2 is formed instantaneously and then reacts with the excess of PdCl 4 2− to form PdCl 3 T − . The reaction follows a second order mechanism. The instability constants of the two compounds and the rate constant are calculated at 25°C. The 3-thiomorpholinone compounds of Palladium and Platinum are examined by means of I.R. spectrophotometry and the resultant spectra are discussed. The results of the enquiry suggest that this category of compounds is most likely to have a square trans- planar configuration in which the ligand is bonded to the metal via sulphur.
