Synthesis and crystal structures of palladium(II) complexes containing benzyl 8-quinolyl sulfide and phenethyl 8-quinolyl sulfide
摘要:
Four palladium(II) complexes [PdX2(L-N,S)] (X = Cl, Br; L: BzSq = benzyl 8-quinolyl sulfide, PheneSq = phenethyl 8-quinolyl sulfide) were prepared. The crystal structure of [PdCl2(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 Me2SO, MeCN and MeNO2. On the other hand, [PdCl2(PheneSq-N,S)] did not show such an intraligand stacking both in the solid and in solutions.
