X-ray crystallographic studies show that varying the nature of the S-aryl ligands in SCS-Pd(II) pincer complexes and the electronic nature of the aryl substituent para to the Pd(II) group in PCP-Pd(II) pincer complexes do not lead to structural changes in these palladacycles that can be correlated with the changing nature of the ligands. While the original C2 symmetry for the S-aryl groups in SCS-Pd(II) pincer complexes seen in the case of the 2,5-bis(thiophenylmethyl)phenylpalladium chloride pincer complex is also seen in other SCS-Pd(II) pincer complexes, the relative stereochemistry of the S-aryl rings is not consistently maintained in 2,5-bis((4-dimethylaminothiophenyl) methyl)-phenylpalladium chloride. © 2005 Elsevier B.V.
