An Example Spectrochemical Series
The acetylacetonate ligand is a common bidentate (binds in two places) ligand for metal complexes.
It is shown here forming an octahedral complex with the Cr3+ metal ion. We have not discussed the
Lewis acid/base properties of the (acac) ligand, so l've provided you with its location in an
abbreviated spectrochemical series. While the overall symmetry does not match this, for the
purposes of this problem we will treat the coordination environment as having O, symmetry.
The K, for (Cu(en),1* is much larger than the one for
(Cu(NH,),]2+. This difference is primarily an entropy effect.
Explain why and calculate the difference between the AS values
at 298 K for the complete dissociation of the two complex ions.
(Hint: The value of AH is about the same for both systems.)
