Abstract
The reactions of sulphur dioxide with the salt K2PdCl4 and the anion [HPd(CO)Cl2]− are described. The complexes were isolated either as salts of Ph4As+ and Ph4P+ cations or as complexes of neutral nitrogen donor ligands (LL). The ligands used were bidentate or tridentate ligands such as 2,2′-bipyridine (bipy), 1,10-phenanthroline (phen), o-phenylenediamine (o-phen) and 2,2′: 6,2″-terpyridine (terpy). Reaction of sulphur dioxide with K2PdCl4 in aqueous ethanol gave an ethoxysulphonyl dinuclear palladium anion, [PdCl2(SO3C2H5]22−, which reacted with nitrogen donor ligands giving the previously known palladium complexes, Pd(LL)Cl2. If sulphur dioxide was allowed to react with Pd(LL)Cl2 complexes suspended in aqueous ethanol, sulphato complexes of the formula [Pd(LL)SO4]·H2O were obtained. Reaction of sulphur dioxide with a solution of the anion [HPd(CO)Cl2]− and then addition of nitrogen donor ligands, led to the formation of sulphur dioxide complexes.
