Abstract: A new iso-amyl benzothiazolyl sulfoxide (ABSO) was synthesized and used inthe extraction of Pd(II) from hydrochloric acid media. Pd(II) was extracted quantitativelyfrom 0.1 M HCl with ABSO in benzene (0.5 M). Ammonia solution (2.0 M) could beused as stripping agent. ABSO and Pd(II) form a 2:1 adduct [Pd (ABSO)₂Cl₂] in theextraction. X-ray crystal structure determination revealed PdCl₂(ABSO)₂ is asquare-planar complex in which ABSO acts as a neutral unidentate ligand coordinatedwith palladium(II) via the thiazolyl N atom.
