Three neutral trinuclear palladium(II) complexes [Ph3PPdCl(μ- 4-PyS)]3 (1), [Cy3PPdCl(μ-PySJ]3 (2) and [(PhO)3PPdCl(μ-4-PyS)]3 (3) (4-PyS = pyridine-4-thiolate) were self-assembled from corresponding metal fragments [R3PPdCl2J2 with lithium pyridine-4-thiolate (PySLi). The crystal structure reveals that: complex 1 possesses a triangular macrocyclic structure in which the distances of Pd(I)Pd(2), Pd(2)-Pd(3) and Pd(3)-Pd(l) are 7.764, 7.684 and 7.944 A, respectively, An equilibrium between trinuclear complex 1 and mononuclear complex (Ph3P) 2PdCl(4-PyS) (4) in solution through coordination and de-coordination of the PPh3 ligand is confirmed by 31P NMR spectroscopy, A comparative study on the Suzuki-Miyaura coupling reaction showed that: complexes 1 and. 2 are more active precatalysts than [R3PPdCl 2]2 complexes without a. PyS group.
