Abstract

This paper is concerned with inorganic solids composed of the partially oxidized platinum chain salts which represent the most extended type of interaction realizable in the 1-D system: that leading to free carriers and metallic-like conductivity. Such systems are typified by the compound K//2Pt(CN)//4Br//0//. //3 multiplied by (times) 3H//2O(KCP). In terms of the known formal oxidation states of platinum ( plus 2, plus 4) the stoichiometry of KCP can be written K//2 left bracket Pt(II)//0//. //8//5Pt(IV)//0//. //1//5(CN)//4 right bracket Br//0//. //3 multiplied by (times) 3H//2O. However, all Pt-sites are equivalent and separated by the extremely short intermetallic distance of 2. 88 A along the left bracket 001 right bracket stacking axis. Thus, strong metal-metal interaction involving the 5d//z2 orbitals, which are the highest lying occupied states, along the c-axis permits the system to attain a fractional, or partially oxidized valence of plus 2. 3. The x-ray structure shows that the charge compensating Br** minus ions are located in the interstices between the left bracket Pt(CN)//4 right bracket stacks. The interstices also contain sites for the alkali ions and water molecules. The paper presents results comprehensive discussion of an experimental study on the subject.
