,560 J. K. \TITTLEAND G.TJRRS of the C=C frequencies modified by coordination to platinum(I1) (ca. 1500 c1ri-l) and palladium(I1) (ca. 1530 cm-l). For both elements, using both ligands, the tendency to form chelate complexes is affected by the anion present; iodide and especially thiocyanate ion tend to displace the coordinated double bond.
This parallels the affinity of various anions for platiiiuni(I1) as derived from an equilibrium study of their reaction with Zeise's anion [C2H4PtC13]-, oiz.,F
