Abstract
The Fe-P bond in low-spin pentacyanoferrates(II) of the type Na3[Fe(CN )5L](L=phosphine or phosphite) has been characterized by P-31 NMR and cyclic voltammetry. The chemical shift in the P-31{H-1} NMR spectra in creases with the redox potential on the cyclic voltammogram. A linear dependence of the chemical shifts on the redox potentials has revealed that the pi-back donation from the iron d(pi)-orbitals to the phospho rus d(pi)-orbitals plays an important role in the character of the Fe- P bond.
