Abstract

The 31P{1H}NMR spectra for a series of pentacyanoferrates(II) of the type Na3[Fe(CN)5L] (L = phosphine or phosphite) have been measured. A low field chemical shift range of 48.1-88.7 ppm for phosphine complexes and of 32.5-48.4 ppm for phosphite complexes is observed when one compares free vs. coordinated ligands. The correlation between chemical shifts in the 31P NMR spectra and isomeric shifts in the Mössbauer spectra is investigated and discussed
