| Abstract: | Summary The kinetics of the substitution reactions of the protonated forms oftrans-tetracyanodioxotungstate(IV) ions with pyridine and thiocyanate ions were studied. The kinetic results were compared with those of the reactions with N

and F– ions and a linear free energy relationship was obtained which was interpreted as additional evidence for a dissociative mechanism. Infrared data for this type of complex are reported and discussed in terms of thetrans influence of various monodentate ligands. |
