Some New 1-D Compounds with Metal-Halide Chain

Abstract

Abstract Some new mixed valence compounds of the type [M(L-L)2M(L-L)2X2]Y4 (where M = Pt or Pd, L-L = 2NH3 or ethylenediamine, X = Cl, Br or I and Y = HSO4, 1/2 SO4, ClO4 or 1/2 PtCl4) have been synthesized. The polarized Raman spectra of single crystals show the anisotropic character and the presence of ---M(II)---X-M(IV)-X chains. The method of preparation and the chemical behaviour correspond to the mechanism of the formation of Magnus green salt oxidized product.
