A comparison of δcalcd 15N NMR chemical shifts with δexptl 15N NMR chemical shifts reveals that the DFT calculations correctly predict the division of signals into two groups, the first one involving the PdII, PtII, and RhIII nitrato complexes, and the second the PtIV and PdIV nitrato complexes. Hydrogen bonds and the number of nitrato ligands and their coordination mode remarkably affect the δcalcd 15N chemical shift.
