Temperature and Larmor frequency dependences of 1H NMR relaxation time T1 were measured in a 1-D halogen-bridged complex [Pt(en)2][PtX2(en)2](C1O4) 4 in ranges of 90 - 300 K and 15 - 60 MHz, respectively. The observed main and long T1 component was explainable by the magnetic dipolar relaxation due to electron spins diffusing along the 1-D chain containing paramagnetic PtIII sites with a concentration of 10-4 in molar ratio. These spins attributed to neutral spin solitons were shown to diffuse more rapidly than those in [Pd(chxn)2][PdBr2(chxn2]Br4 forming 2-D H-bond networks.
