N2 - 31P MAS NMR spectra in the solid state were measured on halogen-bridged one-dimensional complexes (NH4)4[Pt2X(pop)4] (pop: P2O5H2-2; X: Cl, Br, I) together with the corresponding binuclear PtII and PtIII monomer complexes containing [Pt2(pop)4]4- and [Pt2X2(pop)4]4- (X: Cl, Br, I) ions, respectively. The polymer complexes afforded two kinds of 31P resonance lines with chemical shifts of 20-40 and 50-70 ppm, values which are close to those in the monomer PtII and PtIII complexes, respectively. From the analysis of spectra and spin-lattice relaxation data, a mixed-valence -PtIIPtIIX PtIIIPtIIIX- type chain structure was concluded for the polymer complexes.
