Abstract

1H NMR spin-lattice relaxation time T1 of the above complex in the solid state was measured from 100 K to room temperature. The presence of paramagnetic PtIII sites trapped in the 1-D chains was observed at low temperatures. T1 was shortened upon heating, and the observed T1 data were well explained by the model that the trapped unpaired electrons are thermally excited and diffuse along the chain. The observed spin motion is attributable to the neutral soliton by referring to the data of ESR and the electrical conductivity.
