Abstract

We measured NMR and ESR in solid state of a Br₂ doped halogen-bridged one-dimensional mixed-valence complex, {[Pt(en) ₂][PtBr₂(en)₂]}₃(CuBr ₄)₄·12H₂O, which forms a double chain structure consisting of -Pt(II)-Br-Pt(IV)-Br- and -Cu(I)-Br-Cu(I)-Br-, ¹³C NMR measurements gave broad spectra explainable by marked effects from paramagnetic sites assignable to Pt(III) and/or Cu(II) in the chain oxidized by bromine. Pt(III) sites are considered to form neutral solitons by referring to the electrical conductivity result.
