Abstract

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 Pt^III 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.
