Xenon Hexafluoroplatinate - Structure

Structure

The structure of "xenon hexafluoroplatinate" is probably not Xe+−. The main problem with this formulation is "Xe+", which would be a radical and would dimerize or abstract an F atom to give XeF+. Thus, Bartlett discovered that Xe undergoes chemical reactions, but the nature of his initial mustard yellow product is complex. Further work indicates that Bartlett's product probably contained −, −, and . The title "compound" is a salt, consisting of an octahedral anionic fluoride complex of platinum and various xenon cations.

It has been proposed that the platinum fluoride forms a negatively charged polymeric network with xenon or xenon fluoride cations held in its instices. A preparation of "XePtF6" in HF solution results in a solid which has been characterized as a n polymeric network associated with XeF+. This result is evidence for such a polymeric structure of xenon hexafluoroplatinate.

Famous quotes containing the word structure:

    The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.
    —For the State of New Jersey, U.S. public relief program (1935-1943)

    Just as a new scientific discovery manifests something that was already latent in the order of nature, and at the same time is logically related to the total structure of the existing science, so the new poem manifests something that was already latent in the order of words.
    Northrop Frye (b. 1912)

    There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. There is therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.
    Donald Davidson (b. 1917)
