Spontaneous Transfer of Parahydrogen Derived Spin Order to Pyridine at Low Magnetic Field

The cationic iridium complex [Ir(COD)(PCy3)(py)]BF4 (1) is shown to react with dihydrogen in the presence of pyridine (py) to form the dihydride complex fac,cis-[Ir(PCy3)(py)3(H)2]BF4 (2). Complex 2 undergoes rapid exchange of the two bound pyridine ligands which are trans to hydride with free pyrid...
