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