palladium complexes containing the thiocyanate anion as a ligand were studied. Initially, the square planar [Pd(AsPh3)2(SCN)2] complex was synthesized and this was isomerized to [Pd(AsPh3)2(NCS)2] at elevated temperatures and these two complexes were characterized by infrared spectroscopy. To prove with absolute certainty that the changes they observed in the infrared spectra were due to the linkage isomerism of the thiocyanate ligands, they also synthesized and characterized [Pd(bipy)(SCN)2] and [Pd(bipy)(NCS)2], as well as [Pd(bipy)2][Pd(SCN)4] a. Why was it important that they used the bipy ligand instead of the AsPh3 ligands in this study? What type of isomerism would it prohibit from occurring? b. What type of isomerism is observed when comparing [Pd(bipy)(SCN)2] and [Pd(bipy)2][Pd(SCN)4]? Please draw both of the complexes as part of the explanation of your answer.
