The activation parameters for the chair-to-chair interconversion of the six-membered chelate ring of [Fe<SUP>III</SUP>(CN)<SUB>4</SUB>(1,3-propanediamine)]<SUP>−</SUP> have been determined from a line-shape analysis of the <SUP>1</SUP>H NMR spectra of the paramagnetic complex by taking advantage of the large differences in the chemical shift: Δ<I>H</I><SUP>≠</SUP>=32.2±4.6 kJ mol<SUP>−1</SUP>, Δ<I>S</I><SUP>≠</SUP>=31.2±28.6 J mol<SUP>−1</SUP> K<SUP>−1</SUP>, and Δ<I>G</I><SUB>298</SUB><SUP>≠</SUP>=22.9±3.9 kJ mol<SUP>−1</SUP>. The Δ<I>H</I><SUP>≠</SUP> and Δ<I>S</I><SUP>≠</SUP> values are larger by 7.5 kJ mol<SUP>−1</SUP> and 31 J mol<SUP>−1</SUP> K<SUP>−1</SUP> than those of the corresponding 1,2-ethanediamine chelate, [Fe<SUP>III</SUP>(CN)<SUB>4</SUB>(1,2-ethanediamine)]<SUP>−</SUP>, respectively. The kinetic data supported the transition state with a half-boat conformation.
