Synthesis and crystal structures of palladium(II) complexes containing benzyl 8-quinolyl sulfide and phenethyl 8-quinolyl sulfide

Abstract Four palladium(II) complexes [PdX 2 (L- N , S )] (X=Cl, Br; L: BzSq=benzyl 8-quinolyl sulfide, PheneSq=phenethyl 8-quinolyl sulfide) were prepared. The crystal structure of [PdCl 2 (BzSq- N , S )] revealed the presence of an intraligand stacking between the phenyl and quinolyl groups of BzSq. This stacking interaction was confirmed even in Me 2 SO, MeCN and MeNO 2 . On the other hand, [PdCl 2 (PheneSq- N , S )] did not show such an intraligand stacking both in the solid and in solutions.
