The Rubidium-Cesium Partially Oxidized Tetracyanoplatinate Hydrogen Difluoride -Fluoride Systems

THE RUBIDIUM-CESIUM PARTIALLY OXIDIZED TETRACYANOPLATINATE (HYDROGEN DIFLUORIDE)-FLUORIDE SYSTEMS  

The compounds differ in their Pt—Pt intrachain separations, electrical conductivities, degree of partial oxidation of the platinum atom, and metallic color. These major differences occur even though two pairs of these four compounds contain the same anion, (FHF)-, and cation, Rb+ or Cs+. This provides the unique opportunity to explore only the effects of structural, not elemental, changes on the anisotropic electrical behavior of POTCP salts. 

The Cs2 [Pt(CN)4 ] -H20 and Rb2 [Pt(CN)4 ] 1.5H2 0 starting materials for these preparations are synthesized as described by Maffly et al.3 and Koch et al.,4 respectively. The cesium fluoride and rubidium fluoride are 99.9% pure. All other chemicals are ACS reagent grade. Distilled water is used throughout the procedures.
