Mössbauer Spectra of Substituted Pentacyanoferrates(II) Containing Monoprotonated Diamines or Nitrogenated Heterocycles

Abstract

Mössbauer parameters (IS and NQS) for a series of hydrated sodium pentacyano-L ferrates(II) (L = monoprotonated diamines or nitrogenated heterocycles) are presented. Results are discussed in terms of electronic properties of the ligands. A tentative distinction between σ-and π-bonding effects is shown and comparisons are made with previous results reported for related substances
