Diisopentyl Sulphide as an Extractant for Palladium (II) and the Crystal Structure of Palladium(II) Complex

Diisopentyl sulphide (DIS) was used in an extract for Pd(II) from hydrochloric acid media. Palladium (II) was extracted quantitatively from 0.1 M HCl with diisopentyl sulphide concentration, contact time of aqueous and organic phases, organic/acqueous (O/A) phase ratio, ammonia concentration and hydrochloric acid concentratin of aqueous phase, were studied. Diisopentyl sulphide and Pd (II) form a 2:1 adduct (Pd(DIS)(2)Cl-2 in the extraction. X-Ray crystral determination revealed taht Pd(DIS)(2)Cl-2 is square-planar complex in which diisopentyl sulphide acts as a neutral unidentate ligand coordinated with palladium(II) via the sulphur atom of the diisopentyl sulphide.
